Genetic analysis suggests there may have been a long period of cross-breeding between early ancestors of the humans and chimpanzees, before they finally split into the Homo and Pan (chimp) genera around six million years ago.
Humans have one pair fewer chromosomes than other apes, as humans have 23 chromosome pairs, while all other apes have 24, [13] with ape chromosomes 12 and 13 fused in the human genome into a large chromosome (which contains remnants of the centromere and telomeres of the ancestral 12 and 13).
A performing chimp called Oliver brought to the US from Africa was once suspected (or at least marketed) to be some kind of 'missing link' humanzee hybrid, given his reported human-like appearance, ability to walk upright, and preference for companionship with humans.
Researchers haven’t pinned down exactly which mechanisms prevent interbreeding under most circumstances. Some closely related species can mate even if they have different numbers of chromosomes.
It’s weird to think that tens of thousands of years ago, humans were mating with different species—but they were. That’s what DNA analyses tell us.
Human-ape hybrids are genetically impossible, because the two species have different numbers of chromosomes - humans have 23 pairs (46 total) while all great apes (orangutans, gorillas, and chimps) all have 24 pairs, or 48 total chromosomes.
While this scientific advance offers the prospect of growing human organs inside animals for use in transplants, it can also leave some people with a queasy feeling.
