There were BACK & FORTH migrations, because
though eventually we had a lot of different
populations of Homo, the only one that we all
share is the Aquatic Ape ancestor.
Humans do not originate in a place -- Out of Africa
vs Out of Asia -- we originate in an environment. The
Yes. IMO
-aquarboreal Hominoidea originated in coastal forests of the archipelagoes between India & Eurasia c 40?30 Ma (plate tectonics),
-aquarboreal hominids s.l. lived along Tethys Sea coastal forests c 30-6 Ma, -aquarboreal hominids s.s. (HPG) lived in Red Sea coastal forests c 10-5 Ma, -Pleistocene shallow-diving Homo (no "ape" any more) came from the Asian Ind.Ocean coasts: Java, Flores...
"Out of Africa" is nonsense: perhaps late-Pleistocene <80 ka (when we evolved the enzymes for MC- ->LC-PUFAs)?
We underwent 2 drastic anatomical changes vs "monkeys":
1) apes: wading-climbing hominoids after c 30 Ma: bipedalism, very broad sternum & thorax, tail loss, larger body size, centrally-placed spine, arm-hanging...
2) humans: archaic Homo after c 2 Ma: very large brain (x3), pachyosteosclerosis, platycephaly, platymeria... = frequent diving.
Perhaps (1) might have been even more profound than (2), but partly?largely disappeared (partly in parallel, e.g.->knuckle-walking P//G) in (early?-)Pleistocene apes.
Island animals (Indian archipelagoes c 30 Ma) are often anatomically very special (1),
but I don't know if this was also the case in archaic Homo (2), e.g. Flores??
Aquatic Ape is the one that defines us all as "Human"
and it's not about GPS coordinates, it's about the
Littoral/Waterside environment.
Yes.
Stuff *That* in your "Eew, racism!" and smoke it, why
don't you?
