Thanks for this Wm Trevor, I was unaware of that research.

I have always had that nagging feeling that something was missing in my life, and now I know. I shall sleep well tonight.

I feel somewhat cheated, though. Who knows what humans might have accomplished, if only they had been able to hold on to those two chromosomes, and stop them from fusing.

I wonder if they felt it when it happened? Probably a bit like appendicitis, you'd think.
