Embryology in the Quran: Difference between revisions

Proponents of Qur'anic embryology often defend their position by claiming that words like 'alaqah can have several meanings, and that some or all of these meanings apply at the same time. Thus, we hear that the 'alaqah is a leech, or looks like a leech if viewed in a certain angle, or is a leech-like structure, is a clot of blood, or looks like a blood clot, or hangs from or clings to the endometrium. Some of these are genuine definitions of 'alaqah, others are not. Each one is problematic and will be addressed below.

 

The best method of refuting Qur'anic embryology is by questioning every claim as to its validity, and to make its proponents justify every claim. This would include why they chose to make a choice when there are several other equally valid possibilities, why they chose to ignore clearly nonsensical phrases, and why they assume certain phrases to be metaphorical while others to be literal. Some will also benefit from seeing the definitions of the significant words from Lane's Lexicon of classical arabic, cited and linked throughout this article.

 

If, the reader is so inclined, they can read a good summary of the arbitrary assumptions and heavily selective debating technique used by apologists, with a particular focus on Keith Moore's claims, [{{Reference archive|1=http://web.archive.org/web/20060214032231/http://www.geocities.com/freethoughtmecca/embryo.html|2=2011-12-05}} here], and can read the relevant sections [http://embryologyinthequran.blogspot.com here] to see how many of the word definitions used in Islamic apologetics are based on misquotes of Arabic dictionaries and are incompatible with how those same Arabic words were used in the hadith (such as the claims that the word 'alaqah meant a "leech-like substance", that a mudghah is not merely a small piece of meat, but one that has been chewed).

Apologists who are fond of leech metaphors should consider that unlike a leech, which simply sucks blood from its host, the embryo circulates and exchanges blood and waste products with its mother.<ref>Barry Mitchell & Ram Sharma 2009. Embryology: An Illustrated Colour Text. Second Edition. Churchill Livingstone ElSevier. Page 10-11</ref> Furthermore, leeches attach themselves directly to their surface of their hosts. In contrast, the [[w:https://en.wikipedia.org/wiki/Blastocyst|blastocyst]] stage embryo implants into the uterine wall ([[w:https://en.wikipedia.org/wiki/Endometrium|endometrium]]) by means of an outer cell layer, called the [[w:https://en.wikipedia.org/wiki/Syncytiotrophoblast|syncytiotrophoblast]]. It is the syncytiotrophoblast which invades the endometrium, burying the entire embryo within the wall (unlike a leech), establishes a circulatory connection, and will later form the outer layer of the [[w:https://en.wikipedia.org/wiki/Placenta#Development|placenta]].

A leech has many characteristics such as size, behaviour, shape, color, appearance. Why would the author use 'alaqah intending such a metaphorical meaning when his listeners could not be expected to know in what respect the analogy applies? It is a typical Texan Sharpshooter fallacy<ref>{{cite web|quote= The Texas sharpshooter fallacy is an informal fallacy in which pieces of information that have no relationship to one another are called out for their similarities, and that similarity is used for claiming the existence of a pattern. This fallacy is the philosophical/rhetorical application of the multiple comparisons problem (in statistics) and apophenia (in cognitive psychology). It is related to the clustering illusion, which refers to the tendency in human cognition to interpret patterns where none actually exist.

Moreover, such apologetics have to conveniently ignore the embryo's yolk sac, which gradually becomes incorporated into its developing gut, when depicting the embryo.

The poet al-Nabigha alja'di النابغة الجعدي (died c.670 AD), who was a contemporary of Muhammad, in one of his poems says:  

The creator, the maker, the fashioner, in the wombs semen until it becomes blood<ref>{{cite web|url= http://poetsgate.com/poem_14021.html|title= الحمد لله لا شريك له|publisher= PoetsGate (Arabic)|author= |date= February 15, 2007|archiveurl= http://archive.is/6XW6e|deadurl=no}}</ref>}}

This further underlines the suspicion just mentioned, and moreover, suggests some influence in 7^th century Arabia of the ideas of the Greek physician, Galen, whose works were studied at that time by groups in Alexandria and Syria. Indeed, other similarities between Galenic embryology and that of the Qur'an are well known.

In order to compare with science the Qur'anic statement that Allah makes 'ithaman (bones<ref name="LLitham"></ref>) and then clothes (fa-kasawna<ref name="LLkasawa"></ref>) the bones with lahman (flesh<ref name="LLlahm"></ref>), first we should see what science has discovered about the process of bone and muscle formation. Here is a brief description for both of them, without any detail on the relative timing of parallel processes. The section that follows afterwards contains numerous cited scientific sources stating the timing of these processes.

Mesoderm is the middle of the three layers of the early embryo. Some of the mesoderm cells form a series of blocks called somites either side of the neural tube (this tube will eventually form the spinal cord and brain). These somites will differentiate into sclerotome and myotome, which form the cartilage 'models' (or 'templates') and become connective tissues (including muscles) respectively of the future axial skeleton (i.e. everything except the limbs, shoulders and pelvis). The myotome differentiates and migrates as the sclerotome is condensing into mesenchyme, which will produce cartilage. Each process occurs segmentally down the somites in a cranio-caudal sequence (head to tail).

Another area of mesoderm (lateral plate mesoderm) proliferates especially quickly in certain positions to form the limb buds. There, mesenchyme cells condense into distinct masses within the limb buds. These mesenchyme cells differentiate into chondrocytes, which secrete the cartilage matrix and are embedded in it. Thus cartilage models of the future limb bones gradually form (chondrification). Once the cartilage models have formed and while they are still growing, the cartilage is literally replaced with actual bone by osteoblasts (ossification) working outwards from centres of the cartilage models. Osteoclasts remove the remnants of the mineralized cartilage. Ossification also starts in the axial skeleton some time after it has begun in the limbs, except for the upper and lower jaw, which start to ossify slightly earlier.

Meanwhile, the process of limb muscle formation begins as soon as the limb buds appear. Myoblast cells migrate from somites to populate the limb buds. They aggregate into distinct masses, differentiating and fusing into muscle fibres, as the condensing mesenchyme starts to chondrify, and before the resulting cartilage models begin to ossify.  

Secondly, muscle and bone (or their precursors) develop contemporaneously, although the parallel processes start when muscle begins developing around condensations of mesenchyme that have only just begun to diffentiate into cartilage. Therefore, there is no scientific basis for the Qur'anic claim of a stage in which bone is later covered with flesh after its own formation. The prefix fa before khalaqna means "and then", indicating an uninterrupted sequence.<ref>فَ fa - [http://www.studyquran.org/LaneLexicon/Volume6/00000105.pdf Lane's Lexicon] Volume 6, page 2322</ref>

Even if we were to accept that the Qur'an was only referring to precursors of bone and not bone itself, even though it used the Arabic word for bone ('itham), and not cartilage (ghurdoof), the embryology is still wrong. Even if, with further and unjustifiable generosity, we suppose that the Qur'an means only the very beginning of the formation of the cartilage (chondrification) before they are in any sense complete shapes and the beginning of the formation of muscles, even this happens at the same stage (around day 41). Going back earlier still, it can even be pointed out that the precursors of muscles (myoblasts) and precursors to the cartilage (mesenchyme) are present in the limb bud as soon as it arises.  

===Womb has Three Layers of darkness===

The word butun (بطن)<ref>بطن butun - [[http://www.studyquran.org/LaneLexicon/Volume1/00000257.pdf Lane's Lexicon] Volume 1, page 220</ref> means belly/abdomen/midriff, though some translators like to use the more specific word "womb". There are many more layers in the human body such as the endometrium, myometrium, perimetrium, peritoneum, besides the cervix uteri, corpus uteri, abdomen (with walls), and placenta (with layers). The idea of three membranes around the fetus ([[w:https://en.wikipedia.org/wiki/Chorion|chorion]], [[w:https://en.wikipedia.org/wiki/Allantois|allantois]], and [[w:https://en.wikipedia.org/wiki/Amnion|amnion]]) was taught by the highly influential Greek physician, Galen. It is likely that the Qur'anic author is simply repeating this idea, which applies only to the embryonic membranes.

The allantois is a sac-like structure which becomes part of the umbilical cord, hardly a 'veil of darkness'. The other two membranes, the chorion and amnion, together form the [[w:https://en.wikipedia.org/wiki/Amniotic_sac|amniotic sac]], which is quite thin and transparent.

He created you (all) from a single person: then created, of like nature, his mate; and he sent down for you eight head of cattle in pairs: He makes you, in the wombs of your mothers, in stages, one after another, in '''three veils of darkness'''. such is Allah, your Lord and Cherisher: to Him belongs (all) dominion. There is no god but He: then how are ye turned away (from your true Centre)? }}
