A recent article I found discusses a man in China that has only 44 Chromosomes instead of the normal 46 and that in most other ways the man seems normal and that it might well be possible to pass this genetic trait along.

Should that happen, are we seeing an example of speciation in humans?

Actually possible. He is in a small community with lots of close family relationships. First there is a one in three chance of a successful pregnancy when mating with a 46 Chromosome woman and in that case a 50% chance of the child having 44 Chromosomes.
