First off, don't say "no spamming/R/N," because neither I nor Roll have been spamming at all...

First off, "[me] and [my] scientist" do NOT say that we evolved from baboons. If you had actually bothered to READ my post, you'd have noticed that I said we evolved from a COMMON ANCESTOR. Chimpanzees, baboons, gorillas....they're all evolved forms of this COMMON ANCESTOR as well, just not as highly evolved as us humans are. We all started out as Ardipithicus ramidus and then evolved from THAT, taking two separate evolutionary paths along the way.

You continue to ask me the question "why are we not changing anymore," which I have answered over and over. I have said that is not a true statement, nor even accurate. It's possible that we've stopped evolving, as you are claiming, or it's MORE LIKELY that we still are, we just don't see it yet.

Look at the chart. Homo sapiens sapiens (us humans) have only existed for about 200 thousand years. Most other forms of hominal life (read: human-like predecessors) existed for between 200 thousand and 1 million years before evolution occurred. If you take the AVERAGE, the AVERAGE is about 500 thousand years between evolutionary steps.

Humans have only been around for 200 thousand years. Your claim that we have "stopped evolving because our brain is the most evolved of them all (most evolved of them all what?)" has no scientific support whatsoever. You can't make the claim that we've stopped evolving because our brains are more evolved than our predecessors, because if you say that, then according to whatever misguided logic you're going by, then we should never have evolved from Australopithecus anamensis to afarensis, because the anamensis had a more highly evolved physique and brain than the COMMON ANCESTOR, the ramidus.

Yes, our brains are more highly evolved than our evolutionary predecessors. Is that proof, or even evidence, that there is no higher evolutionary "next step?" NO!

Our brains may be more highly evolved than our previous evolutionary forms, but they're still FAR from perfect. Look at alligators, crocodiles and sharks....they've remained virtually unchanged for over 100 million years. THAT is evolutionary perfection, or as close as it'll get. To say that humans are no longer evolving becuase we havn't seen change in 200 thousand years when there are other creatures who have remained unchanged for 100 MILLION years is an unbacked, unsupported, and unintelligent claim.
