From the cited by you article ...=20

"Using neutral estimates of primate LTR divergence [8], we estimate that a =

What you talk about is therefore retrovirus that infected those apes separa=
tely
and anyway after human ancestors had already split/stopped hybridising with
ancestors of those apes. Why are the viruses relevant?

Pliocene Africa they only find "human ancestors"... :-DDD Don't they reali=

The cited article mentions australopiths in precisely zero places so it is =
unclear from
where you even took them in. By other publications australopiths appeared 4=
.2 mya
well before of those retroviruses entered genomes of said apes. If australo=

did. Those places are in Africa and those tools weren't likely made by chim=
panzee or
gorilla. Instead you are discussing 2.2 mya or younger stuff from time when=
tools are
all over the place: =20

Particularly you cherry-pick Java with findings 1.8 mya old. Why?

And again your straw-man without source. What is the source of that antelop=

garbage? You never tell. Yet your whole "aquarboreal" theory is built on fa=

between those unknown "cheetah men" and your unknown "deep ones". Without c=
