By-the-way, a "Big Bang" in art is supportive of ID and undermines gradualistic human evolution. It is not the "final nail in the coffin", but it is one more bit of evidence that favors the ID side, eh? Every new thing could be claimed as a product of ID. Agriculture, fire, the wheel, use of metals, etc. ID is such a wonderful answer. But I prefer to give all the credit to Prometheus. (Why let man have any credit at all?)
I personally think that the biggest advantage our immediate ancestors had vis-a-vis the other "human" lines was the development of language.
