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?
There were rumors of a human/chimp hybrid decades ago:

Despite the existence of Oliver, it still seems unproven:

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