I was wondering if Homo sapiens could ever stop evolving at all (both physically and culturally). I mean look how far we've come:
Homo afranseis--->Homo habiliis (I think that was "Lucy" IIRC)-->Homo erectus-->Neanderthals-->Hello, Homo sapiens. We've come a long way from stone tools in the developed world (knives, forks, etc), and of course-we've got clothing. Our skulls have had changed dramatically over those years as well.
But...can we ever stop evolving physically and culturally? I can't imagine how mama nature could ever find another reason for us to improve, as we have all this technology around us.
And...is evolution just a theory and/or hypotheses?
