That's not an answer to his question. The lad wants to know the means and mechanisms, not non-specific statements no better than "because God said so." He wants to know why a chimp or orangutan was better suited to its environment than Neanderthals.
One fraction of the answer may be that lesser primates never competed with humans like Neanderthals may have and were on the loosing end of that struggle.

Why haven't humans lived in the jungles where gorillas live?
They do. Who else do you think is poaching them?
Hominids weren't good at living in the niche that apes lived in. True, today we can live anywhere due to our technology, but do you think a family of man could survive in the jungles along side apes without any modern conveniences like guns or weapons and modern tools? I don't think so.
Well, there are cases of ferrel children being born in the wild and raised by wolves, so it is conceivable that they could survive.
But where are you going with this?
