  • The LCA looked like Homo, not Pan

    From JTEM is so reasonable@21:1/5 to All on Wed Jun 14 00:37:38 2023
    Want to find the LCA? Start looking for something that
    looks like Homo... something upright, for starters. The
    LCA was upright, walked bipedally... looked like Homo
    or at least like an australopithecine...

    Mainstream paleo anthropology is all about protecting
    their castle from the unwashed masses. It has nothing
    to do with science what so ever. It compares chimps
    living RIGHT! NOW! Lucy & kin and concludes the LCA
    had to look exactly like a present day Chimp, because
    a present day Chimp doesn't look too too much like
    Lucy...

    It's backwards. It's like those idiots who keep seeing
    "Bird like traits" in dinosaurs even though the dinosaurs
    and the traits are significantly older than birds.

    Chimps did now exist millions of years ago. They have
    evolved for as long as we have since the LCA. And the
    LCA was bipedal.

    Jesus Christ, people, I put the LCA far, Far, FAR more
    recent than most people, and even I say 3.7 million
    years ago! So even with my more-recent-than-your
    date, Chimps have evolved for 3.7 million years AFTER
    the LCA.

    Clearly, by your own reckoning, the LCA looked
    absolutely NOTHING like a Chimp!

    :-) Yes, Mio-Pliocene hominids were not very chimp-like, but also not very humanlike.
    Many animals remain millions of years +-unchanged (e.g. "lizards"),
    but hominids (Gorilla, Homo & Pan) underwent apparently a lot of changes Plio-Pleistocene.
    But what is usu.not well understood is that Pan & Gorilla evolved largely in parallel since their common ancestor:
    already >30 years ago, I proposed that they evolved knuckle-walking in parallel:
    only after a few decades, that seems to be +-generally accepted by now... :-) -- Pan // Gorilla evolved from bipedally wading-climbing aquarboreals in the Pliocene to quadrupedal knuckle-walkers today.
    -- Homo went a very different evolution (mostly early-Pleistocene??): our ancestors evolved from aquarboreal to shallow-diving.

    Homo's evolution, in short, schematically, IMO:
    -wading+climbing: Pliocene "vertical" S-Asia, google "aquarboreal", -wading+diving, early-Pleist.H.erectus->Java, google "pachyosteosclerosis", -wading+walking, late-Pleist.H.sapiens, google "gondwanatalks verhaegen".
