Answer 1

With apes, as others have mentioned, it’s because our last common ancestor was approximately 6 million years ago.

We were, however, able to breed with other hominids during the time hominids were developing. And later, when the homo sapiens subspecies developed, there is evidence that modern humans interbred with the recognized human subspecies: Neanderthals and Denisovans.
