Sciences: "Darwin’s mistake: explaining the discontinuity between human and
nonhuman minds," by Derek C. Penn, Keith J. Holyoak and Daniel J.
Povinelli.
Their abstract:
"Certainly from the ground up, there are signs of God. And your own as well.do not see?"
After Chris of Mixing
Memory and Deric
Bownds of Deric Bownds' Mindblog had already drawn attention to the prefinal
version of this article, “Darwin’s
mistake: Explaining the discontinuity between human and nonhuman minds” by
Derek
Penn, Keith
Holyoak and Daniel
Povinelli has now finally been published in the current issue of the Behavioral
and Brain Sciences.
Penn, who’s affiliated with the Cognitive
Evolution Group at the University of Louisiana, and the University of
California, Los Angeles, Holyoak, Professor of Psychology at the University of
California, and Povinelli, Professor of Biology at the University of Louisiana,
and also a member of the Cognitive Evolution Group, argue that
“Over the last quarter century, the dominant tendency in comparative
cognitive psychology has been to emphasize the similarities between human and
nonhuman minds and to downplay the differences as “one of degree and not of
kind” (Darwin 1871). In the present target article, we argue that Darwin was
mistaken: the profound biological continuity between human and nonhuman animals
masks an equally profound discontinuity between human and nonhuman minds. To
wit, there is a significant discontinuity in the degree to which human and
nonhuman animals are able to approximate the higher-order, systematic,
relational capabilities of a physical symbol system (PSS) (Newell 1980). We show
that this symbolic-relational discontinuity pervades nearly every domain of
cognition and runs much deeper than even the spectacular scaffolding provided by
language or culture alone can explain. We propose a representational-level
specification as to where human and nonhuman animals’ abilities to approximate a
PSS are similar and where they differ. We conclude by suggesting that recent
symbolic-connectionist models of cognition shed new light on the mechanisms that
underlie the gap between human and nonhuman minds.”
As was to expected the article sparked quite a lot of heated responses in the
comment section both for it’s title and for its discontinuist view of human
cognitive which emphasizes the large gulf that lies between human and nonhuman
cognition. Those who are afraid that again a creationist/ID paper has made it
into a respectable science journal, can calm down. In their first footnote Penn
et al. make clear that:
"All similarities and differences in biology are ultimately a matter
of degree. Any apparent discontinuities between living species belie the
underlying continuity of the evolutionary process and largely result from the
fact that many, and often all, of the intermediate steps are no longer extant.
In the present article, our claim that there is a “discontinuity” between human
and nonhuman cognition is based on our claim that there is a significant gap
between the functional capabilities of the human mind and those of all other
extant species on the planet. Our point, to cut to the chase, is that the
functional discontinuity between human and nonhuman minds is at least as great
as the much more widely acknowledged discontinuity between human and nonhuman
forms of communication. But we do not doubt that both evolved through standard
evolutionary mechanisms. (Penn et al. 2008: 129)
Interestingly, when you google “Darwin’s
mistake” your fist hit is an amazon link for a book called “Darwin's
Mistake: Antediluvian
Discoveries Prove Dinosaurs and Humans Co-Existed” to which I won’t link because
I don’t want to raise the page rank of such junk. The second link is a funny
little poem called "Darwin's mistake",
which goes like this:
“Three monkeys sat on a coconut tree
Discussing things as they're said to be.
Said one to the others, "Now listen, you two,
There is a certain rumor that can't be true
That man descended from our noble race.
That very idea is a disgrace.
No monkey ever deserted his wife,
Starved her babies or ruined her life.
And another thing you will never see:
A monkey build a fence around a coconut tree
And let the coconuts go to waste
Forbidding all the other monkeys to taste.
If I put a fence around this tree,
Starvation would force you to steal from me.
Here's another thing a monkey won't do:
Go out at night and get on a stew,
And use a gun, or club, or knife
To take some other monkey's life.
Yes, man descended, the ornery cuss -
But, brother, he didn't descend from us.”
I must say this poem is actually pretty funny (given that it's not meant as
anti-evolutionary propaganda), although, as primatologists and the Machiavellian
intelligence hypothesis tell us, non-human primates
surely
aren’t saints either.
But Penn et al. make their scientific standpoint absolutely clear with the
title of their response, which is called:
“Darwin’s triumph: Explaining the uniqueness of the human mind
without a deus ex machina”
I am particularly excited by the comment of Graeme Halford,
professor emeritus at the University of Queensland, Australia, and his
colleagues, who write that they
“agree with Penn et al. that the ability to recognise structural
correspondences between relational representations accounts for many distinctive
properties of higher cognition. We propose to take this argument further by
defining both a conceptual and a methodological link between animal and human
cognition. The conceptual link is to treat relational processing (Halford et al.
1998a) as dynamic bindings of chunks to a coordinate system in working
memory (Oberauer et al. 2007). Such a coordinate system consists of slots
and relations between them, and includes relational schemas (Halford &
Busby 2007)” (Halford et al. 2008: 138)
This of course reminds me of Karl Bühler’s (1934) coordinate system of
subjective orientation which I
tried to use as a starting point for
a cognitive theory which sees mental representations as intersubjectively
overlapping and thus shared systemic spaces in
the form of a cognitive coordinate system/frame of reference into which and in
which conceptual representations are imported, integrated, unified, and
blended. In the future, I will have another look at both Penn et al.’s and
Graeme Halford’s claims.
Another ‘interesting’ comment is that of R. Allen Gardner, a
Professor of Cognitive and Brain Sciences at the University of Nevada, Reno.
Here’s the abstract:
“Sound comparative psychology and modern evolutionary and
developmental biology emphasize powerful effects of developmental conditions on
the expression of genetic endowment. Both demand that evolutionary theorists
recognize these effects. Sound comparative psychology also demands
experimental procedures that prevent experimenters from shaping the responses of
human and nonhuman beings to conform to theoretical expectations.” (Gardner
2008: 135).
What now, you may ask, is ‘interesting’ about this article?. Well let’s take
a look at what agrdner had to say about another important Paper on the
difference between human and nonhuman cognition, namely Tomasello et al.’s
(2005): Understanding
and Sharing Intentions: The Origins of Cultural Cognition:
“Sound comparative psychology and modern evolutionary and
developmental biology (often called evo-devo) emphasize powerful effects of
developmental conditions on the expression of genetic endowment. Both demand
that evolutionary theorists recognize these effects. Instead, Tomasello et
al. compares studies of normal human children with studies of chimpanzees reared
and maintained in cognitively deprived conditions, while ignoring studies of
chimpanzees in cognitively appropriate environments.” (Gardner 2005:
699)
To me this sounds a bit like flogging a dead horse, but what do I know. (not
much about evo-devo, that’s for sure)
At least both feature this nice photo of the test apparatus for chimpanzee
Basso, who first was believed to be able to count but, as was found out in 1917,
instead was only reacting to the unconscious cues of the experimenter:

Premack offers a stimulating brief essay (PDF here
) pointing out that recent
cognitive studies finding abilities in animals once thought unique to humans
should not lead us to confuse similarity with equivalence, for the human brain
has nerve cell types and connections not found in any other animals. He examines
eight cognitive areas to argue that dissimilarities are large. Here is his
abstract:
Microscopic study of the human brain has revealed neural
structures, enhanced wiring, and forms of connectivity among nerve cells not
found in any animal, challenging the view that the human brain is simply an
enlarged chimpanzee brain. On the other hand, cognitive studies have found
animals to have abilities once thought unique to the human. This suggests a
disparity between brain and mind. The suggestion is misleading. Cognitive
research has not kept pace with neural research. Neural findings are based on
microscopic study of the brain and are primarily cellular. Because cognition
cannot be studied microscopically, we need to refine the study of cognition by
using a different approach. In examining claims of similarity between animals
and humans, one must ask: What are the dissimilarities? This approach prevents
confusing similarity with equivalence. We follow this approach in examining
eight cognitive cases—teaching, short-term memory, causal reasoning, planning,
deception, transitive inference, theory of mind, and language—and find, in all
cases, that similarities between animal and human abilities are small,
dissimilarities large. There is no disparity between brain and
mind.
Over the last quarter-century, the dominant tendency in
comparative cognitive psychology has been to emphasize the similarities between
human and nonhuman minds and to downplay the differences as “one of degree and
not of kind” (Darwin 1871). In the present paper, we argue that Darwin was
mistaken: the profound biological continuity between human and nonhuman animals
masks an equally profound discontinuity between human and nonhuman minds. To
wit, there is a significant discontinuity in the degree to which human and
nonhuman animals are able to approximate the higher-order, systematic,
relational capabilities of a physical symbol system (Newell 1980). We show that
this symbolic-relational discontinuity pervades nearly every domain of cognition
and runs much deeper than even the spectacular scaffolding provided by language
or culture alone can explain. We propose a representational-level specification
of where human and nonhuman animals’ abilities to approximate a PSS are similar
and where they differ. We conclude by suggesting that recent
symbolic-connectionist models of cognition shed new light on the mechanisms that
underlie the gap between human and nonhuman minds.
Errors in Darwin's Dangerous Idea
Daniel C. Dennett
As of January 25, 2006, readers have identified the following errors in Darwin's Dangerous Idea. (I have considered other criticisms offered by readers, but decided that they were in error. Further criticisms are, of course, invited.):
P24. I describe Aristotle’s Prime Mover as a final cause, but this is incorrect; Aristotle’s Prime Mover is the efficient cause of all things. Pointed out by Chris Hammel, 1/23/06.
p57. "Simulated annealing" may be a misnomer, since the process I describe--and describe blacksmiths as employing--is signicantly different from standard annealing practices. source: John Verhoeven.
p97. My argument about how to identify Mitochondrial Eve (ME) is flawed. This has been pointed out by Ian Gillies, Bill Margolis, Chris Viger, and Gilbert Scott Markle. (See also, the useful discussion in Jack Cohen and Ian Stewart's new book Figments of Reality). There are two complications, which I will call multiple local MEs and grandmother stacks.
Multiple local MEs: There could in principle be long periods of "stasis" in which the sets of mothers of mothers of . . . . didn't shrink in size for hundreds or thousands of years on end. No set can be larger than its successor, but it needn't be any smaller. In such a circumstance, going backwards in time, the "remaining" lineages each funnel down to a "local ME" (with two daughters) and that local ME's mother, (maternal) grandmother, greatgrandmother and so forth, single-file lineages marching back into the past. Whenever two such local ME strands converge, they discover a "new," less local ME, discharging their two more local double-daughtered MEs. In principle such multiple local ME strands could go back to multiple independent origins of mitochondrial life (of eukaryotes)--but there is very good reason to suppose that global ME (the True Mitochondrial Eve) is a hominid of some ilk, if not a member in clear standing of H. sapiens. I was wrong to suggest (by saying the sets "must" contract") that such a twin-lineage (to take the simplest case) couldn't "go on forever"; in principle it could, but with negligible--but not Vanishing--probability.
A grandmother stack is a subset of women related by maternity within any of the sets A, B, C, of mothers of mothers . . . . Thus in set B, the mothers of people alive today, there is the following grandmother stack: Andrea (mother of my grandson), Susan (my wife), Ruth (my mother-in-law), and her mother, the late Sylvia. Set C will drop Andrea and add Sylvia's mother, and so forth. Subsequent sets will always have a four-member grandmother stack generated by today's contemporaneous generations in my family. There are probably some seven- or eight-deep grandmother stacks somewhere in the world today, but I would think that the biological limit is about nine (you can get a ten-deep stack by assuming a stack of 13-year-old mothers with a still living 104-year-old ancestor). When local MEs evaporate by coalescence in the manner described above, the grandmother stacks involved do not shrink in the sets in which they appear. But the number of distinct grandmother stacks diminishes. When we reach Mitochondrial Eve, we will go right by her, since when she first appears she will be a member of a set of at least four women (Brandon's maternal ancestors) and probably seven or eight or nine. But this will quickly be apparent, since soon enough all members of the set will be a single grandmother stack, and we can locate ME as the only one with two daughters in the previous set.
p122-23. The standard account of the QWERTY phenomenon, as presented here (and by Papert and Gould and others), has been challenged by S. J. Liebowitz and Stephen E. Margolis, in "The Fable of the Keys," Journal of Law and Economics, 33, April 1990, pp1-25. source: [I have misfiled the letter that drew this article to my attention. My apologies, whoever you are.] But see also Jared Diamond's article, "The Curse of QWERTY," in Discover, April 1997, pp. 34-42, and the further bibliography he lists on the last page, including the web site http://ww.ccsi.com/~mbrooks/dvorak/dvorak.html. Diamond, in a letter to me, finds grounds for disagreeing with Liebowitz and Margolis, so the issue remains unresolved.
p126. H. Allen Orr says: "Population genetic theory, for instance, does not prove that evolution by random change is faster than evolution by natural selection." ("Dennett's Strange Idea," Boston Review, 21, Summer 1996, p28.) I misspoke, but the result was ambiguity, not error. If we compare regions of DNA that are under selection pressure with regions that are not, we discover that ON AVERAGE, the regions that are under selection pressure show a lower rate of change--because of stabilizing selection. That is, when a new selection pressure is introduced, this typically leads to a relatively short, rapid burst of change followed by a long period of near stasis. If you stop the race at fixation time, then of course evolution by natural selection looks faster than random drift, but that is an artifact of the time window chosen. In his reply to my original clarification of this point in the Boston Review (October/November, 1996, p37), Orr claimed not to know what I was talking about, and rudely suggested-- "I can find no polite way of putting this"--that I didn't either, but when I gave him this elaboration of my intended meaning, he acknowledged that it was not mistaken, but that in the context he had not considered it.

p271. Robert Mark's fine article, "Architecture and Evolution," in the July-August 1996 issue of American Scientist (pp383-389), shows that I underestimated the structural demands of support for a large dome over arches, so that my bracket diagram (the middle diagram in Figure 10.3) would not be sound, lacking the necessary surcharge. Squinches would also not be sufficient, he claims, for such large, heavy domes. His final conclusion is that my "treatment of crucial structural elements as a kind of surface decoration that can be altered at will--'You have to put something there to hold up the dome--some shape or other, you decide which"--ignores the years, or in some cases even centuries, of construction experience that led to their incorporation in historic buildings." In other words, according to Mark, the pendentives of San Marco are very definitely structural adaptations, not Gouldian "spandrels". This point is elaborated upon by Alasdair I. Houston, in "Are the spandrels of San Marco really panglossian pendentives?" in Trends in Ecology and Evolution, March 1997, 12.
p.274. Robert Mark (see above) also criticizes my claim that the bosses in the fan vaults of King's College Chapel could have been replaced by "neat round holes," but see the letter from Stephen Grover, and Robert Mark's reply, in American Scientist Nov/Dec 1996, p518. As Grover points out, Walter C. Leedy's 1980 book Fan Vaulting does support me on this, and Patrick Bateson, Provost of King's College, has also written to me supporting my account.

Decidedly not Latin in their roots, they are . . . sometimes nearly unpronounceable. . . . Walcott, who loved the Canadian Rockies, . . . labeled his fossils the the names of local peaks and lakes, themselves derived from Indian words."

p360. Richard Feynman is wrong! As Irwin Tessman, Department of Biological Sciences, Purdue University, points out in a letter to Nature ("Feynman faux pas," 381, 30 May, 1996, p361), "The example he gives would not prove replacement; in fact, it suggests quite the opposite. In an endearing lapse, Feynman appers to have blanked out on the half-life for the decay of 32P to sulphur, which just happens to be two weeks; if the radioactivity decreases to one-half in two weeks it means (within experimental error) that there was no turnover of phosphorus in the cerebrum."
p370. Goethe did indeed say it, in Faust. Mephistopheles says, in Part I:
Denn eben wo Begriffe fehlen,
Da stellt ein Wort zur rechten Zeit sich ein.
Ernst Mayr was the first to draw this to my attention, and his citation from memory [!] was almost exactly correct. Simon van der Meer also sent me the German text, and Wolfgang Heinemann provided me with the Wayre translation:
For if your meaning's threatened with stagnation,
Then words come in, to save the situation:
They'll fight your battles well if you enlist 'em,
Or furnish you a universal system.
Thus words will serve you grandly for a creed,
Where every syllable is guaranteed."
p488. Many readers have urged that I am wrong about which cards need to be turned over in the Wason test, but it is they who are mistaken--which just goes to show how powerful this cognitive illusion is. However, Simon van der Meer finds fault with my expression of the task: I should have said "Your task is to find all exceptions to the rule" (since otherwise, one could sometimes find an exception by just turning over the first card).

THE MOON'S ORBIT
And We have decreed set phases for the moon, until it ends up
looking like an old date branch. It is not for the sun to overtake the moon nor
for the night to outstrip the day; each one is swimming in a sphere. (Qur'an,
36:39-40)
The Moon does not follow a regular orbit like the satellites of other
planets. As it orbits the Earth, it sometimes moves behind it and sometimes in
front. As it also moves with the Earth around the Sun, it actually follows a
constant pattern resembling the letter "S" in space. This route, traced by the
Moon in space, is described in the Qur'an as resembling an old date branch and
does indeed resemble the twisted form of the date tree branch. Indeed, the word
"urjoon" employed in the Qur'an refers to a thin and twisted date branch and is
used to describe that part left after the fruit has been picked. The way that
this branch is described as "old" is also most appropriate since old date
branches are thinner and more twisted.
Since the Moon revolves around the Sun together with the
Earth, it follows a path through space which resembles the letter “S.” The appearance of this orbit resembles the twisted shape of a dry date branch, as is revealed in the Qur’an. |
There is no doubt that it was impossible for anyone to have any knowledge
about the orbit of the Moon 1,400 years ago. The way that this pattern,
identified by modern technology and accumulated knowledge, was revealed in the
Holy Book is yet another scientific miracle of the Qur'an
ATOMIC ENERGY AND FISSION
Allah splits the seed and kernel. He brings forth the living from the dead, and produces the dead out of the living. That is Allah, so how are you misguided? (Qur'an, 6:95)
The terms "seed" (al-habb) and "kernel" (an-nawa) in the above verse may indicate the splitting of the atom. Indeed, the dictionary meanings of an-nawa include "nucleus, centre, atomic nucleus." Furthermore, the description of bringing forth the living from the dead can be interpreted as Allah creating matter from dead energy. Producing the dead out of the living may refer to energy (dead) emerging from matter (living), since the atom is in motion. (Allah knows best.) That is because as well as "living," al-hayy can also mean "active, energetic." With its meaning of "non-living," al-mayyit, translated above as "dead," may very probably refer to energy.
Scientists define energy as the capacity for doing work. Matter, the material that comprises all things on Earth and in the universe, consists of atoms and molecules that can be seen to be in motion under an electron microscope. In the early twentieth century, Albert Einstein (d. 1955) theorised that matter could be converted into energy, suggesting that the two were inter-related at the atomic level.199 This may be the bringing forth of the dead from the living, as described above, or, in other words, obtaining energy from matter, which is in motion at the atomic level. In addition, yukhriju, translated as "bringing forth," also means "bringing out, emitting" (as in the case of electrical waves). Therefore, the terms in this verse may be indicating the form of energy obtained from the atom. (Allah knows best.)
Today, atomic nucleus can be split into smaller nuclei by means of nuclear fission. |
Scientists can now split the atom by dividing its nucleus. Taking Einstein's theories as their starting point, they obtained energy from matter in the 1940s by means of nuclear fission, the process of splitting the atomic nucleus. The verb faliqu in Surat al-An`am 95, translated as "to split," may be a reference to fission's dictionary meaning: the process of splitting (the atom's nucleus). When this process takes place, enormous amounts of energy are released.
The words in Surat al-An`am 95 are very wise in terms of their meanings. The phenomena described in this verse bear a very close resemblance to the splitting of the atom's nucleus in order to obtain atomic energy. The verse may therefore be a reference to nuclear fission, which was only made possible by twentieth-century technology. (Allah knows best.)

THE CLONING OF LIVING THINGS
[Satan said:] “I will lead them astray and fill them with false hopes. I will command them and they will cut off cattle’s ears. I will command them and they will change Allah’s creation.” Anyone who takes satan as his protector in place of Allah has clearly lost everything.” (Surat an-Nisa’, 119)
The above verse contains the expression “yubattikunna,” which derives from the verb "battaka” meaning ”to cut off or break off.” The term “yughayyirunna” in the verse derives from the verb “ghayyara,” meaning “to change, alter, impair a thing’s original form.” At the end of both verbs appears the confirmatory letter ”nun.” With these expressions, verse 119 of Surat an-Nisa’ may, in one aspect, be pointing to the scientific activity of copying or cloning of organisms. (Allah knows the truth.) That is because cloning experiments are generally conducted with cells taken from an animal’s ear. To put it another way, a replica living thing is produced with the taking of cells from tissue samples “cut from animals’ ears,” just as described in the verse.
A report by the German Federal Agricultural Research Center provides the following information:
The tissue collection phase is short and simple. Once an animal has been located and restrained, a tissue sample like an ear clipping can be collected within seconds. Furthermore, somatic cells can be collected from all species. … For cattle, pigs, sheep, goats, camelids and llamas, a unified and identical procedure can be used by obtaining a tissue sample from the ear using notchers which are also used for setting earmarks… Clearly, for all species lymphocytes could be used, but somatic cells from ear clippings will be much easier to obtain and are therefore preferable. 1
Some reports concerning organisms cloned by taking samples from ear tissue include:
- According to a report by Reuters dated 1 May, 2002, a research veterinarian at the University of Sao Paolo in Brazil, Jose Visintin, produced cloned embryos for the first time in the country by using cells taken from the ear of an adult cow.2
- According to a BBC report, South Korean scientists cloned a dog called Snuppy from cells taken from a 3-year-old Afghan hound. Researchers at the Seoul National University extracted genetic material from the cells taken from the ear and placed it into an empty egg cell. An embryo was then obtained by stimulating the cell to divide.3
- Another BBC report said that a new clone had been produced using ear cells from an adult cow in research carried out by Dr. Jean-Paul Renard et al. at the Institute National de la Recherche Agronomique in France.4
- According to information of the official Human Genome Project website, in February 2002, scientists from the Advanced Cell Technologies (ACT) biotechnology company carried out experiments on cloning a cow embryo using the skin cell of the donor cow’s ear.5
- A report by Associated Press, dated 24 January, 2000, announced that Japanese scientists had cloned the clone of a bull for the first time. In the re-cloning, skin tissue samples from the first generation cloned bull’s ear were taken when it was four months old. These cells were then fused with an unfertilized egg from which the nucleus had been removed.6
The way that changes in the creation of living things are referred to in the Qur’an and the expression “cutting off cattle’s ears,” at a time when no branches of science such as genetics or embryology existed, shows that the Qur’an has come down from the Sight of our Lord, Allah, Who is unfettered by time. We are also told at the end of the verse that these people will be disappointed when they alter what Allah has created. The verse may therefore be indicating that cloning will give rise to various problems for human beings. (Allah knows the truth.) Indeed, statements from the Genetic Science Learning Center of the University of Utah provide the following information:
When we hear of cloning successes, we learn about only the few attempts that worked. What we don't see are the many, many cloning experiments that failed! And even in the successful clones, problems tend to arise later, during the animal's development to adulthood.7
Information from the Human Genome Project website take this form:
Dolly, the first mammal to be cloned from adult DNA, [died on] Feb. 14, 2003. Prior to her death, Dolly had been suffering from lung cancer and crippling arthritis. … More than 90% of cloning attempts fail to produce viable offspring. … In addition to low success rates, cloned animals tend to have more compromised immune function and higher rates of infection, tumor growth, and other disorders. Japanese studies have shown that cloned mice live in poor health and die early. … Appearing healthy at a young age unfortunately is not a good indicator of long term survival. Clones have been known to die mysteriously. For example, Australia's first cloned sheep appeared healthy and energetic on the day she died, and the results from her autopsy failed to determine a cause of death.8
In general terms, the risks arising from cloning experiments are as follows:
1) A high failure rate: The level of success is just 0.1%-3%. That means a failure rate of 970-999 for every 1000 experiments.9
2) Problems during development: Cloned animals that do survive generally have abnormally larger organs compared to the originals. This may lead to respiration and circulation difficulties, unhealthy kidneys and brain, and an impaired immune system.
3) Abnormal gene expression patterns: Although clones have the same DNA sequences as the originals, the cell nucleus in the clone does not have the same program as that in a natural embryo. To put it another way, the DNA cannot express the right set of genes essential for the development of the clone at the right time. For example, cells of all kinds, nerve, bone, blood or skin for example, all have different programs but the genetic programs in the clone embryo do not work as healthily as those in a natural embryo.
4) Telomeric differences: Chromosomes are shortened as cells divide. The reason for this is that DNA sequences at both ends of a chromosome, known as telomeres, are shortened during each DNA replication. As an animal grows older, the telomeres shorten as part of that aging. Therefore, the copied life form has shortened chromosomes from the moment it is born, just as if it were actually older.
Genetic material taken from living cells is used in cloning experiments, but fertilization takes place artificially. The reproduction mechanism created by Allah is thus impaired with these methods, and unidentified diseases, developmental deficiencies and early deaths are encountered. The way that it was reported 1400 years ago that scientists would engage in cloning and that the problems awaiting people therefrom are emphasized, clearly reveals that the Qur’an is a Divine scripture.
In the cloning process, DNA from a cell of the living thing planned to be copied is placed under the microscope and placed into an egg cell from another member of the same species. The DNA of the animal intended to be copied is used for this. An electric shock is then applied, which stimulates the egg cell to start dividing. The embryo continues to divide and is placed into the womb of a member of the species, and is then left to develop and be born.

8- Then made his offspring from the quintessence of the nature of a despised fluid.
32-The Prostration, 8
In the 46th chapter, our attention was drawn to the fact that man was created from a quintessence of clay. The Arabic meaning of the word, “quintessence” is “sulala.” Just as man is created from a “quintessence” of the earth, he is also created from a “quintessence” of semen. While the word “drop” signifies just a small amount of semen, the word “quintessence” draws attention to the essence of semen. Sperm constitute only a part of the semen, in fact they are the basic element of it. The particular sperm that fertilizes the egg is but a tiny member of hundreds of millions of sperm in semen; it is also the swimmer that reaches the finish, having overtaken all the others. Each of us is the winner sperm’s product. Every human being coming to the world has behind him hundreds of millions in this swimming race. We, who are reading these lines, have come out victorious, since we are far ahead of those we have left behind. Each of us has carried the day. And we are the quintessence!
57- It is We who created you, so why do you not affirm the truth?
58- Do you then see the semen that you emit?
59- Is it you who create it or are We the creator?
56-The Inevitable, 57-59
DETERMINATION OF THE CHILD’S SEX
45- That He did create in pairs, male and female;
46- From a drop of semen which emitted.
53-The Star, 45-46
Even today there are still people and families on the husband’s side who blame mothers for giving birth to girls rather than to boys. That it is the mother who decides on the sex of her child is a lingering prejudice among the ignorant. Although well-informed scientific circles were exempt from such misconceptions, even they had until quite recently the impression that the child’s sex was the joint product of equal contribution by the mother’s egg and the father’s sperm. The fact that it is the sperm that determines the child’s sex has only recently been established. In a fabricated hadith falsely attributed to the Prophet, we read: “Male’s water is white. Woman’s water is yellow. If the two come together and the man’s water overcomes the woman’s, a male child is born, if, on the other hand, it is the woman’s water that dominates, the child is a girl.” One can see that during and centuries after the time of the Prophet the factor that determined the sex of the child was not known.
The implication in the Quran of the formation of sex is astounding, as it indicates that it is a drop of semen that determines it. The 46 chromosomes that human cells contain form the genetic code of a human being. Two of these determine the child’s sex. Male chromosomes are defined as XY and the female ones as XX. The chromosomes are split during ovulation into two each, containing an X chromosome. Some sperms contain X and some Y chromosome. If an X chromosome unites with an X chromosome in the woman’s egg, the sex of the child to be born will be female, while a Y chromosome in man uniting with an X chromosome in woman means the offspring will be of the male sex. We see that whether the future child will be a boy or a girl is entirely dependent on the arrival of an X or Y chromosome from the sperm. Biological research continues. The discovery in the1990s of the SRY protein in the Y chromosome, and the conclusions derived from it, have enriched the available data on the issue. This information that the Quran implied more than 1400 years ago was not known until quite recently. We can mention, for example, the story of Henry the VIII, who divorced Catherine his queen for having 168 given him a girl child. This fact, alluded to in the Quran, had also an ironical touch. Women have been blamed for centuries for having been responsible in the determination of the sex of the child they were going to give birth to. The discoveries of science have explained this miraculous event, while ruling out the grounds which put the blame on the woman.
SECURE PLACE
20- Have We not created you from an unassuming fluid?
21- The which We placed in a secure place.
77-The Emissaries, 20-21
The uterus is described as a secure place. Being placed in the center of the pelvic cavity, it is well protected. Man’s organ is not favored with such an endowment. The uterus is a cavity whose walls are made of muscles and have the shape of a pear. In an adult woman the length of it is 8cm, the width measures 5cm and the height 2.5cm. The uterus, relatively small in size, dilates considerably during the last phase of pregnancy. The weight of it is 50gr while it attains about 1000 gr at the end of pregnancy. The child it holds within it can even exceed 5000 grams. This means that the child is 100 times heavier than the uterus itself.
It is the only organ that can grow so rapidly and is given to rapid development. With its tightly wedged thick muscles, it protects the fetus, rapidly growing in size, against all kinds of external impacts and adverse conditions. The fetus, exposed to all sorts of dangers, owes its survival to the solid structure of the uterus, its ideal place. The
Quran’s drawing our attention to the solidity and durability of the womb calls for our studying it more deeply is a proof of the God whose grace protects the fetus against all ill intentions.

CLOUDS AND THE PROCESS OF RAIN
43- Do not you see that God drives the clouds, then joins them together, then piles them on each other, then you see the rain comes forth from between them. And He sends down hail from the sky, where there are mountains of it. And strikes those with it whom He will and diverts it from whomever He wills. The vivid flash of its lightning nearly blinds the sight. 24-The Light, 43 Water is life. The greater portion of water that is the basic need for the living beings on earth is in continuous motion and transformation. The uninterrupted sequence of these successive transformations is referred to as cycling. Water is always present in the air. It goes without saying that this state of water differs from its state in the seas and rivers. The formation of clouds by water in the state of vapor, the transformation of these clouds into rainwater and their falling upon the earth as precipitation are the result of God’s impeccable cycling system. More than 1400 years ago, the Quran began to draw our attention to the facts that today can be established only by the help of satellites. Scientists studied types of clouds and established that they were the consequence of well-designed systems and stages. Meteorologists examined the cumulonimbus clouds. The stages they described tallied with the process described in the sura The Light, verse 43. 1- Clouds move thanks to winds: The fact that the wind is the primary cause in the process of the formation of clouds that generates rain is depicted in the sura, The Romans, verse 46 (In the previous chapter, we saw the role played by wind in the formation of clouds). 2- Joining: Then the small clouds combine to form a single large cloud. 3- Piles them on each other: When the small clouds join together, updrafts within the larger cloud increase. The updrafts near the center of the cloud are stronger than those near the edges. These updrafts cause the cloud body to grow vertically, so the cloud is stacked up. This vertical growth causes the cloud body to stretch into cooler regions of the atmosphere where drops of water and hail formulate. When these drops of water and hail become too heavy for the updrafts to support them, they begin to fall from the cloud as rain, hail, etc.
THE FECUNDATING WINDS
In one verse of the Qur'an, the "fecundating"
characteristic of the winds, and the resulting formation of rain are
mentioned.
And We send the fecundating winds, then cause water to descend
from the sky, therewith providing you with water in abundance. (Qur'an,
15:22)
This verse points out that the first stage in the formation of rain is wind.
Until the beginning of the 20th century, the only relationship known between the
wind and the rain was that it was the wind that drove the clouds. However,
modern meteorological findings have demonstrated the "fecundating" role of the
wind in the formation of rain.
As explained earlier, this fecundating function of the wind works in the
following way:
On the surface of oceans and seas, a large number of air bubbles form because
of the water's foaming action. The moment these bubbles burst, thousands of tiny
particles, with a diameter of just one hundredth of a millimetre, are thrown up
into the air. These particles, known as "aerosols," mix with dust carried from
the land by the wind, and are carried to the upper layers of the atmosphere.
These particles carried to higher altitudes by winds come into contact with
water vapour up there. Water vapour condenses around these particles and turns
into water droplets. These water droplets first come together and form clouds,
and then fall to the Earth in the form of rain. As mentioned, winds "fecundate"
the water vapour floating in the air with the particles they carry from the sea,
and eventually help the formation of rain clouds.
If winds did not possess this property, water droplets in the upper
atmosphere would never form, and there would be no rain.
The most important point to be recognized here is that this critical role of
the wind in the formation of rain was stated centuries ago in the Qur'an, at a
time when very little was known about natural phenomena…
The picture above shows the stages in the formation of a wave. |
Further information provided in the verse about the fertilising quality of
the wind is its role in the pollination of flowers. Many plants on Earth
disperse their pollen by means of the wind in order to ensure the survival of
their species. Several open-seeded plants, pine trees, palm and similar trees,
seeded plants that produce flowers, and grass-like plants are entirely
pollinated by the wind. The wind carries the pollen from the plants to others of
the species, thus fertilising them.
Until recently, the way that the wind was able to fertilise plants was
unknown. When it was realised, however, that plants are divided into males and
females, the fertilising role of the wind was also discovered. This truth was
already indicated in the Qur'an: "… [He] sent down water
from the sky by which We have brought forth various different types of plants in
pairs." (Qur'an, 20:53)
13- Then We placed him as a drop in a firmly established lodging 14- Then We developed the drop into a hanging... 23-The Believers, 13-14
“Alaq” is the Arabic word referring to something that is hanging on a place. Embryology did not exist as a science at the time of the Prophet. Neither was there special terminology yet. The Quran described the stages using the words current at the time. According to this description, the zygote then hangs on the wall of the uterus. The Quran brings clarification to something unknown at the time. To render the word “alaq” with the signification ‘embryo’ may not exactly reflect its original meaning, and would moreover fail to convey the spirit of it. To translate it as “a clot of blood” deviates from the literal meaning of the word. This rendering has often been adopted, giving it the attribute of a secondary meaning of the word. The reason was the failure of exegetists to conceive the true meaning of the word. In 1641, Harvey’s statement, according to which the origin of every living thing was an egg, and saying that the embryo underwent transformations, passing through stages of development, was one of the major contributions to the advancement of science. In the 17th century, when man already had the microscope at his disposal, the respective roles of the egg and of the sperm were topics of discussion. Bonnet (1720-1793) speculated that female eggs consisted of a countless number of smaller eggs, one inside the other, and generalized on the “preformation theory,” which maintains that a child arises from an adult in miniature contained within the egg, and he applied this theory to all animals. This hypothesis found many adherents in the 18th century. Men, some thousand years prior to the 18th century, had been acquainted with the Quran. What was said in it about the reproduction of the human organism was rendered in a clear expression that was to take man centuries to confirm. Keith Moore, anatomy professor in the Toronto University of Canada, says that the information contained in the Quran about embryology cannot be accounted for by the data available in the 7th century. He goes further and says that, even a century back, this was hardly known. Only today are we in a position to understand what the verses of the Quran meant, thanks to the development of modern embryology. In history, the only book that exactly describes the development of the human being within the womb is the Quran. Let us once again tackle the subject of hanging to the uterus wall. Only after the invention of the microscope was man able to bring this fact to light as a result of developments in the fields of physiology, anatomy and embryology.
PROOFS FROM THE STAGES OF THE EMBRYO6- These are the signs of God which We rehearse to you in truth. Then in which word other than God and His signs do they believe? 45-Kneeling, 6 The sperm that encounters its other half in the fallopian tube continues its way from there toward the uterus. The embryo, in its journey, does not cling on to the fallopian tube. The embryo proceeds on, and when it reaches the uterus hangs onto a spot where the blood vessels are dense. The stage of “alaq” referred in the Quran has started. How is it that this powerless cell devoid of all intelligence eventually finds for itself a shelter in the uterus, the ideal place for it? How is it that the embryo that arrives at the uterus hangs on its wall and is able to receive all the nourishment necessary for its development, like a leech? (One of the meanings of the word “alaq” is “leech.”) All these things are carefully planned by God’s ingenious artistry. Those who are blind to this fact and refuse to see in this God’s doing, interpreting it as pure coincidence or the embryo’s genius, will be in a ridiculous situation. The process of the embryo hanging on the uterus wall is the result of a complicated system. To penetrate the acid layer of the uterine wall, the embryo secretes an enzyme (hyaluronidase) that catalyzes the uterine tissue and allows the penetration of the embryo, which settles in it like a plant. Henceforth, it will supply its need for food and oxygen from this very point. The hyaluronidase secreted by the embryo catalyzes the breakdown of the hyaluronic acid. Furthermore, the embryo releases some chemicals to protect itself from the mother’s immune system, which would otherwise treat the embryo as a foreign invader to be destroyed. The embryo’s discovery of the place where it is going to hang is a marvel. The embryonic cells have so many activities to perform that a scientist who studies them can easily come to the conclusion that they are entities of high intelligence. 1. Read in the name of your Lord who created 2. He created man from a hanging. 96-The Hanging, 1-2
