Earliest Humans ability to Think

Saw a very interesting series on Primitive mans ability to think just now. Seems that the earliest modern humans lived around 90000 years ago in souther africa.
Thier is evidence of symbolic artwork, that would lay to waste the Human revolution theory which states that primitive man began to " think " 30000 years ago suddenly. It seems man gradualy evolved speech and thinking patterns.

Nice Find. Deep.

But, we can't forget the fact that they have not found any other manmade artifacts nearby.

With his small discovery, but interesting, we can't come to any conclusion. Bummer.
