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.
