[FONT="]Hi,
[/FONT][FONT="]
[/FONT] And What about their interpretation of that Quranic verse( about how the muscles are formed before the bones, but the Quran contradicts it, something along those lines)? This site is kinda confusing to me, and I just wanted some clarification. And then it goes onto talk about the 5 stages or so of development ( about the blood clots etc), is that correct? I read that Zakir Naik had a widely publicised debate( which he supposedly won) with Dr. William Campbell on this issue. It states that the 5 stages of development were common knowledge prior to the revelation of the Quran. But I dont think that is true, and the site seems to me to be a hate attack against Islam. But I was just wanting some clarification thats why.
Thanks

Bones grow first in the embryo or muscles?
Given that the formation of muscle and bone are complex, multistep processes, I am not sure that it is very meaningful to ask which takes place first. We might define the first step in "bone formation" as the first expression of Cbfa1 (now Runx2) in mice. This gene is necessary for the determination of osteoblasts. Yet this occurs in an embryo in which there is already a cartilagenous model of the bone. Why wouldn't that be the first step in bone formation?
Similarly, we might define the first step in "muscle formation" as the expression of the muscle- specific bHLH (basic helix-loop-helix) proteins like MyoD, or the first fusions of myoblasts to form myotubes.
Depending on how we define the first step in muscle and bone formation, we will get different answers on which occurs first.

Besides;
Just as the Qur'anic text suggests: فَخَلَقْنَا الْمُضْغَةَ عِظَامًا فَكَسَوْنَا الْعِظَامَ لَحْمًا - then We created the Mudghah into bones THEN covered the bones in flesh. The 'Fa' which is 'translated' as 'then' shows that this happens simultaneously after that. ie. A happens then suddenly B happens. This is what the 'Fa' implies.
So the Qur'anic description itself recognises that both grow at a similar time and close to each other in sequence.
