Did you know that humans have one less pair of chromosomes than the other apes?
At some point (slightly less than a million years ago iirc) someone was born with two chromosome pairs fused end to end - and it not just worked but worked so well it took over completely for the whole population. So it had to have been at least initially fully compatible with not having them fused, or else that person wouldn't have had fertile kids. -
