Humans descending from primates First, I’ll address the arguments presented of man descending from other primates.

In terms of the probability that only one female is the progenitor of all, I’m going to ask Zeeby in my next post about that.

We cannot observe accumulations of genotypic/phenotypic variation which occur on super-human timescales.

Oldowan The Oldowan is significant for being the earliest stone tool industry in prehistory, being used from 2.6 million years ago up until 1.7 million years ago, when it was followed by the more sophisticated Acheulean industry. Oldowan tools were therefore the earliest tools in human history, and …
