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?
While we did fuck them a lot, knowing us, I don’t think that’s what caused their extinction.
It’s not really called “extinction” from more modern understanding I guess, more like assimilated over a long period of time and from species contact and living with each other.
