All I can do is give my opinion based on the scientific evidence and what I think Why do you think I was asking for others' opinions on the subject dun dun . I wanted to see what OTHERS THINK But your the one with a PHD and who was a teacher, and I am just hillbilly with a Ged education. I am sure your much smarter then me . Just like how you said oxygen is needed for combustion. Your clearly very intelligent and above me lol.
But I will offer my opinion, Oliver appears to be a mutation 1 of a kind as no other chimps have been found with his appearance or abilities or his DNA . He as its different from chimps DNA but the chromosomes are the same.
Its possible he is the next step in chimp evolution but there is no rea evidence of that sense he is the only one. He is decently a chimp and not a human hybrid as some idiots think as his chromosomes prove. However his DNA is different his scent is different .
In my opinion he is a genetic mutant one of a kind.
