Hi, Wikipedia doesn't agree with you:

> Prehistory [...] is the period of _human_ history between the first known use of stone tools by hominins c. 3.3 million years ago and the beginning of recorded history with the invention of writing systems.

Emphasis mine on "human".

Yes, you are right. I was thinking in the context of human populations. And then there is the question of what is human and what is not, and the limit between archaeology and paleontology when considering homininae.
