This paper beautifully confirms my view:
Hominoidea are aquarboreal: bipedally wading+climbing (shortened & centrally-placed lumbar spine, very wide sternum, thorax & pelvis + dorsal scapular, no tail: they predom.moved vertically).
The extant hominid (Homo-Pan-Gorilla) LCA lived aquarboreally in swamp forests, apparently in the incipient Red Sea late-Miocene:

Plio-Pleistocene E.Afr.australopith anatomy is most gorilla-like, but the S..Afr.apiths look more like chimps & bonobos (see a lot of refs in my Hum.Evol.papers 1990, 1994, 1996, 2000):
-- Gorilla fossil subgenus Praeanthropus followed then (8-7 Ma?) the incipient northern Rift ->Afar: anamensis, afarensis (?incl. bahrelghazali, deyiremeda, platyops, antiquus=Lucy), ghari, aethiopicus=walkeri & boisei...
And when the Red Sea opened into the Gulf of Aden (6-5 Ma),
-- Pliocene Pan subgenus Australopithecus went ->right: the eastern African coastal forests -> incipient southern Rift ->Transvaal: africanus, sediba, robustus, naledi, habilis... ("habilis" with small brain, curved phalanges etc. is no Homo, of course, but fossil-hunters prefer to find "Homo" rather than fossil relatives of Gorila or Pan...),
-- Pliocene Homo then went ->left: the southern Asian coasts (H.sapiens has no Pliocene African retroviral DNA),
and on the Indonesian islands, early-Pleistocene archaic Homo were shellfish divers: enamel wear by sand & shells, ear exostoses (water irrigation), pachy-osteo-sclerosis (for shallow-diving e.g. Sirenia) colonisations of Flores & Luzon far oversea, shell engravings (google "Munro Joordens"), brain-size x2 (DHA), fossilisation amid coral & edible shellfish, stone tools (cf sea-otter), "fast"(coastal) intercontinental dispersal already early-Pleistocene to Asia, Europe & Africa (+ via rivers inland //).

Did Hominoidea & Cercopithecoidea split (late-Oligocene?) when Arabafrica approached Eurasia, which initirally formed island archipels + coastal forests, which then were colonised by the early "apes", who became aquarboreal?
Hylobatids soon followed the southern Asian coastal forests ->East.
Pongids & hominids split c 14: Mesopotamian Seaway Closure:
-- sivapiths-pongids -> S.Asia Ind.Ocean coastal forests (forced hylobatids higher into the trees??),
-- dryopiths-hominids -> Med.Sea-coasts of Europe (or dryopiths N-Med? hominids s.s. S-Med?) -> late-Miocene Red Sea HPG hominids, see above.

A few not very important corrections:
