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?
Homo sapiens are the last remaining species of hominina. Our closest remaining relatives, the Pan (chimpanzees and bonobos) diverged at least 6.5 million years ago. Though there is some evidence early hominina may have interbred with pan after the divergence as recently as 4 mya.
This is more recent than dogs and foxes by a long way, and about the same as donkeys and horses. That, plus chromosomal analysis and some other research suggests it could be possible for a human and chimp or bonobo to interbreed, though likely not create fertile offspring. However, there has never been a confirmed case of this occurring, despite multiple claims.
Edit: useful articles:
Pretty sure that we can’t breed with chimps and generate a fertile offspring due the mismatch on the number of chromosomes.
So after reading the wiki, I believe the most likely successful attempt will be to mate a human with downe syndrome, with a chimpanzee. Let’s get on this. I wanna see some atrocities of nature.
The wiki says it’s hard with chimps because we have one less chromosome than chimps. Down syndrome: “all my homes got extra chromies”. They have an extra chromosome. Ergo: down syndrome + chimp = hybrid chimpmanzee.
For the sake of completeness:

We’re talking way earlier than cavemen. The last interbreeding between our ancestors and chimps’ ancestors happened (using the most recent estimate I could find) a million years before the least recent evidence of the use of any stone tools. This is not a human that would be recognisable at all as a human.
