"You Share 98.7 Percent of Your DNA With This Sex-Obsessed Ape" That dimwit has no clue what you are talking about! Too much in the problem! :-)

Sure, Denisovans & Neanderthals were humans. They had human DNA. OTOH, all the great apes have a different number of chromosomes than we do (24 pairs vs our 23 pairs). That's a pretty obvious difference. Assuming we're descended from someone with 24 pairs and two of the pairs fused together, how did this happen? And why aren't there any humans left with 24 pairs of chromosomes? Why should they die out and only humans with 23 pairs survive? It's statistically unlikely an entire group of humans would experience an identical simultaneous mutation that fused two chromosomes together, so the mutation must have first appeared in one single individual. But how did that individual reproduce and pass on the fused chromosomes to children? When meiosis occurs, the chromosomes from the mother and father are lined up and joined together. Which doesn't work very well when there are different numbers of chromosomes? Chromosome fusions produce either sterile individuals and or when reproduction is possible the fusion isn't passed on.
