Chimps are a recently evolved species that descend from an
Aquatic Ape population of Asian origins.
:-)
JTEM, that's only half the truth: the Red Sea = 1/2 African + 1/2 Asian:
1) early-Miocene Hominoidea in swamp forests were already bipedal = vertical waders-climbers,
2) Mio-Pliocene Hominoidea lived along N-Tethys Ocean coasts (hylobatids & pongids still live in SE.Asia),
3) we have always been waterside, cf. physiology, anatomy, diet+DHA, island colonizations, intercontinental dispersals etc.,
4) - E.Afr.apiths resemble Gorilla > Pan > Homo,
- S.Afr.apiths resemble Pan > Homo or Gorilla (e.g. my Hum.Evol.papers).

This explains “ape” anatomy:
- larger size,
- complete tail loss,
- very broad sternum+thorax+pelvis (lateral arm+leg movements),
- centrally-placed (not dorsally) = vertical spine
- etc.
Plate Tectonics & Hominoid Splittings:
~30 Ma Arabafrica approaching Eurasia formed island archipels + coastal forests++.
~25 Ma stem-Hominoidea reached these islands, became wading bipedally + climbing arms overhead: google "aquarboreal".
~20 Ma hylobatids began following N-Tethys coastal forests -> S-Asia.
~15 Ma the Mesopotamian Seaway Closure split pongids-sivapiths (E: N-Ind.Ocean) & hominids-dryopiths (W: Medit.Sea),
~10 Ma hominids s.s. (Gorilla + Homo-Pan) colonized the incipient Red Sea swamp forests.
~8 Ma N-Rift fm, followed by Gorilla -> Afar -> Praeanthropus afarensis Lucy etc. -> boisei -> today G.gorilla & G.beringei.
~5 Ma the Red Sea opened into the Gulf (Francesca Mansfield: caused by Zanclean mega-flood 5.33 Ma?) split Homo & Pan:
– Pan went right: E.Afr.coasts -> S-Rift -> Transvaal -> Australopith.africanus -> robustus (// Gorilla) -> P.troglodytes+paniscus,
– Homo went left: S.Asian coasts -> Java early-Pleist.H.erectus shallow-diving for shellfish:
- pachy-osteo-sclerotic skeleton = shallow-diving
- ear exostoses = chronic colder water irrigation
- shell engravings in Dubois’ erectus collection
- dental wear caused by shellfish: Towle cs 2022
- Pleistocene colonisations of Flores & Luzon
- brain size 2x apes+apiths: DHA etc. in sea-food
- fossilised amid barnacles & edible shellfish
- stone tool use & dexterity = sea-otter
- platy-cephalic skull = hydro-dynamic streamline
- ...
IOW, only *complete* imbeciles still believe their ancestors ran after antelopes... :-DDD
