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.

      Genetic testing basically puts a large amount of doubt on it though. More likely it wasn’t a hybrid than was.

      The Nazis & the Japanese experimented with this as well. AFAIK neither faction ever achieved anything resembling success. Fertilization occurs, but then immediately stops as there’s no compatibility, and the cells die.

      Why else would I ask that question? Completely unrelated, but you happen to have any goats nearby, do you?

    Conventional prehistory says there used to be animals we could interbreed with, but that we in fact bred with them so much that the hybrids replaced the creatures made to get said hybrid.

    These replaced peoples were, of course, designated members of the homo genus, which Homo Sapiens (the scientific name for humans) gets its name from, and they include things such as (using their common names, not their scientific names) Neanderthals (geographically found in Southern Europe), Denisovans (found mostly to the West, towards Asia), and Hobbits (yes, hobbits, they were found in the Pacific). Nothing of note happened in America.

    The Neanderthals and the Denisovans are of particular note, as their territories overlapped commonly, and there are cave findings that show they themselves interbred with each other and produced perfectly functioning offspring. I can only hope when they were engaging in the act, they asked to mingle and ended it with “no homo”.

    There are, however, reports that, at the same time in prehistory, we did try to breed with other animals that haven’t been replaced, typically the great apes, as evidenced by lice samples found in both us and them, but that this, quite expectedly, didn’t lead to any hybrid outcomes.

    I assume closely related hominids which are now extinct. Neanderthal DNA is present in current human strains, which means they didn’t even speciate (though potentially successful gestation was rarer).

    Why am I writing like an alien nerd observing humans?

    No.

    The biological definition of a species is “a group of organisms that can interbreed and produce fertile offspring” (in other words, the offspring need to also be able to reproduce; there are instances, such as mules, where two species reproduce but the offspring cannot themselves reproduce)

      I don’t think that definition matters, considering the fertility of offspring is irrelevant to OP’s question.

      Now that I’m middle aged… How old is Steve Jaleel in this clip? I’ve seen so much of his face that I can’t tell if he’s 15 or 25.

      Note: how have I never known his name is Jaleel White?

      Note 2: Family Matters aired from when he was 13 to 22 years old. So… That’s my answer.
