I now agree with Michel Odent that we probably evolved from 'Marine Chimpanzees', and my term 'Marine Ape' is less appropriate. 

I will now try using the terms 'Marine Chimpanzees' and 'Marine Paleohumans' in my model of Bioko ancestors.

See my revised pdf at paleohuman.com

(Ear exostoses suggest that even European Neanderthals were Marine Paleohumans.)
