One thing for sure, we need more bones! They are hard to get at in portions of the violent Northeast of Africa.
Monkey bones as well. This week’s New Science “Monkey archaeology’ reveals macaque’s Stone Age culture” Macaques have been using an to some degree shaping stone tools. And they a 25 million years away from a common ancestor with us.
Yeah, I didn’t post that one, for one thing, I’m not a fan of the macaque, or to tell the truth, of the chimp either (the latter use sharp sticks to kill and eat bushbabies).
