Ok, I got it. But the real drop in Y chromosome diversity happens 10kya. That's when female sexual selection was really stifled.

You'd expect a rate of increase proportional to the larger base or continuation of the earlier trend of rapid increase in Y chromosome diversity but at 50kya, it slows - implies an increase in violence sufficient to offset the increase (but not yet enough to cause a drop)
