Can a whale produce kids with a monkey? They're both mammals. Just like humans. Hell for that matter could a human have kids with a monkey? Our closest genetic match.  No, I don't think a humanoid could produce healthy offspring with a primate. But a tiger can produce healthy offspring with a lion. Although this would NEVER happen in the wild, it will only happen if you take them and throw them in a cage together when they're in heat. In a natural setting...free from brainwashing via the Marxist controlled media and universities there would be no multi-racial, race mixing societies. The whole concept is unnatural, this is why multi-racial societies are doomed to fail, this is why multi-racial societies are chaos. Birds of a feather flock together and eagles do not fly with pigeons.
