Science P*rn.

This kind of thing happens regularly with fossil discoveries.

We get comfortable with some fact - Homo Sapiens evolved 200,000 years ago - and, then, something comes along that knocks everything akilter.

Fossils discovered that move human origin back to 300,000 years ago. 

Seems like we weren't living up to our potential for some 295,000 years of that time.

Why not?
