Or put differently, 8-10 thousand years ago, the number of men reproducing dropped significantly. That makes sense to me given that this is the period in human history where society begins to form into agrarian communities [1]. The beginnings of social stratification would likely impact reproductive trends.
Saying that the development of society caused more sexual competition among men isn’t crazy. This study basically uses Y-chromosomal tracing to support that point.
