Ok, I am not supporting bestiality here. But, I just came to know about a Dogxim, a dog fox hybrid and I had known for a long time that horses and donkeys can breed (to produce a mule). So, I was just curious, can humans breed with any other animals closely related to us?
As other commenters point out, not since the extinctionof Neanderthals, Denisovans, etc. But even if it were possible, the hybrid would not be fertile: our chromosome 2 is a fusion of two chromosomes that are separate in other related species, so there’s no way meiotic crossover recombination could possibly work.
