I am far to busy these days, with my studies.
Give me some time, maybe a few days or more, and I will respond to this.
Otherwise Answering Islam.org has a good and detailed response to Qur'anic embryology.
Also we from history, that the Greek scientists had great insight into Embryology, and made the same conclusion as the author of the Qur'an.
There were whole schools of embryology at Muhammad's time, furthermore we know that Muhammad had contact with the Christians of era and arae, which where Syrian Greeks, and who were experts in embryology as they emphasised Galen.
We know also that a Christian who supposedly became a Muslim, helped Muhammad compose the Qur'an.
There is also a debate on this forum between Loki and H20, if someone has time to find it and post it here.
Anyway let me come back to it later.
Be blessed
