Oh this is interesting, but how do we get identical twins then? How come we get two gastrulation processes doing the exact same dance side by side, if not DNA?

Also I didn't know about Copy Cat. Being a clone and coming out nothing like the original, what a cat thing to do. They'll wiggle out of anything, them adorable bastards.

Identical twins are only further proof that DNA is not identity, since they have the same DNA but different identities.

The article suggests that the environment plays a significant role in gasturlation, especially the chemistry.

If identical twins develop in the same uterine environment, there would be greater likelihood of the same genes expressing.
