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, a leech attaches itself directly to the surface of its host. 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.

It is related to the clustering illusion, which refers to the tendency in human cognition to interpret patterns where none actually exist.

===Fetus is in Three Layers of darkness===
===Fetus is in 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". Tafsirs interpreted the "three darknesses" as the placenta, womb (uterus) and belly. There are in fact 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. Perhaps 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 'a darkness' for the embryo. 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.
