What would be interesting is if a humanzee turns out perhaps to be just as intelligent and perhaps fitter than humans due to hybrid vigor? Nobody really knows how intelligent a humanzee might bee.
I see his chimp hybrid and raise him from hominid to hominin.
The Homo sapiens neanderthalensis genome is complete enough by now that we could arguably do the same thing with a Neanderthal man.
I think that could well be more informative to mankind's understanding of itself, and likely to cause less suffering for the created individuals.
Not that I particularly agree that either is a good idea.
Attempting to clone a Neanderthal hybrid (because there is no Neanderthal mother anymore so epigenetic is wrong) would probably be a better idea. Should tell us more about their capabilities.
They should also be relatively possible to integrate into society. As opposed to uplifted chimpanzee.
