:-) Thanks, my boy. Some *explanations/corrections* by me:
> =E2=80=A2 Sahelanthropus ('Sahel Man', 'Touma=C3=AF' TM-266, 7=E2=80=936 =
Ma) is about halfway between Pierolapithecus and a small gorilla: conspicuo=
usly *heavy* eye-protective forehead ridge (~18 mm thick), brain no larger =
than in chimps ( ~365 cc), canine teeth smaller, molar enamel thicker, almo=
st like orangutans. Not a real *biped*, thinks Macchiarelli (2020), and Mar=
c Meyer (2022) also finds the strongly curved ulna chimp-like. The fossil c=
omes from a lake deposit in Chad, *at the time* a palm-rich freshwater area=
with fish, water turtles, monitor lizards, pythons, crocodiles, peacocks, =
swans, herons & snake-necked birds, various otters, porcupines & porcupines=
, slim monkeys, antelopes & giraffes, three-toed horses, pachyderms of all =
kinds, the anthracothere 'hippopotamus' Lybicosaurus emerged from the shall=
ow seas of the Lybian Sirt Basin (Lihoreau 2006, Louchart 2008, Munro 2010,=
Novello 2017).=20

My little little boy (grow up!! inform a bit!!), again, for the Xth time: I=
MO
-Mio-Pliocene Hominoidea were "aquarboreal"(google!!): BP wading-climbing i=

-early-Pleist.H.erectus frequently dived (you can call that "semi-aquatic")=
: brain++, pachyosteosclerosis, shell engravings, stone tools, island colon=
izations etc.,
okidoki??
> =E2=80=A2 Orrorin (Milennium Man ~6 Ma), discovered in 2000 by Martin Pic=
kford's group in Kenya, was in a water forest (~1200 mm/year of rain) with =
hippos, slender monkeys, impalas & swamp antelopes, and another great ape o=
ne thinks, divers & water pygmy deer, three-toed horses & chalicothere odd-=
toed ungulates, round-toothed boars & elephants, arboreal hyraxes, palm civ=
ets, galagos, megabats, arboreal & other rodents, lagomorphs & rhinoceroses=
, large otters, various fish & freshwater mussels. Orrorin appeared more hu=
man- & chimp-like than Sahelanthropus, says Professor Pickford, and had cli=
mbing & bipedal features: a vertical vertebral column? The large femoral he=
ad appeared more human-like than in australopiths & apes. The long thigh-bo=
ne helped the leg move sideways, but hindered running. Femoral neck & thigh=
-bone were flattened anterior-backward as in fossil humans & australopiths =
(but less than in seals), not round as in apes, certainly not laterally fla=
ttened as in animals that run a lot. The terminal phalanx of the thumb was =
wider than in chimps, as in us, but not as wide as in boisei. A hand-bone w=
as clearly curved: hanging climbing? The face was short, the molars seemed =
rather small, the tooth-enamel (with wear as in us, unlike in chimps) was t=
hicker than in Sahelanthropus & certainly Ardipithecus. Isotopes in tooth e=
namel indicated a hippo- or boar-like diet (Roche 2013).
The primeval hominids Sahelanthropus & Orrorin mainly ate fruits & *water(s=
ide)* plants, I suspect, often climbed overarms, walked & waded more often =
than lowland gorillas on 2 legs in wetlands, or sometimes floated in shallo=

Yes, my boy, indeed: you talk incoherent word salad.

Google "aquarboreal", my boy, and then come back!
Rest of your salad snipped.
