Well said as always, dear Captain!
Modern experts in human embryology confirm the leech like appearance of the early embryo.
To cite one example, Dr. Keith Moore of Toronto, the foremost embryologist in the world, has made changes in his textbooks (‘Before We Are Born’, ‘Clinical Embryology’) to mention the Quran’s ‘Alaqah’ (leech-like lump of flesh), seeing a picture of leech and comparing it with the early appearance of the embryo.
23:13 Then We placed him as the male and female gametes in a safe lodging.
23:14 Then We fashioned the gametes into zygote, then a leech-like mass of flesh, then the hanging little lump, the embryo. Then We created bones within the embryonic lump, and then clothed the bones with flesh. (Thus, We designed it into a fetus). And then We made it into a new creation (the human infant). So Blessed is God, The Best of creators.
71:14 He is the One Who has created you in successive stages.
22:5 O Mankind! If you are in doubt that one day you will be resurrected back to life after death, consider the process of your own evolution. We have created you in stages: From dust, then from male and female gametes, then from a zygote, then from an embryo, shapely and first shapeless. We thus clearly explain things for you. The embryo and then the fetus stay in the womb until an appointed term according to Our laws. Then We bring you forth as infants and carry you to maturity. While some of you die young, others live to the feeblest old age so that they know nothing after knowing much. You see a dry barren land, but when We send down water on it, it vibrates with life and grows all kinds of beautiful plants.
[Recapturing the earlier stages of evolution, We initiated life from inorganic matter, the clay, then hydrated clay. Through it We brought forth the single life cell, the unicellular organism. Then We created the male and the female cells. Thus procreation came into play. Male and female gametes join, a clot, a little lump of flesh, turning into the embryo that ‘hangs’ in the womb. The embryo is partly formed and partly unformed, until it becomes the fetus and then assumes the final evident proportions.
