Time for a fresh thread Boab?

The evidence (genes, fossils, language etc) strongly suggests Homo Sapiens Sapiens, us, all of us, evolved in Africa around 2,000,000 years ago. Those people, our ancestors, were on average as intelligent or otherwise as we are.

The change in intelligence had been evolving from way back and many current studies explore what caused that change. Lots of good popular but scientifically sound books can be found through Amazon or big book stores.

I will go and see what I have but I bet others will chip in here soon.

Cheers
