One Male for Every 17 Females?! Did the Younger Dryas Cause the Y-Chromosome Bottleneck?

摘要
Back in 2015, Monika Karmin et al produced a paper titled: “A Recent Bottleneck in Y-Chromosome Diversity Coincides With a Global Change in Culture”, linked below, which showed that thousands of years ago, there was a drastic drop in the relative number of males in the global population.
Both scientists and independent researchers have looked into this, giving their own interpretations of the data, why it could have happened, including Antonio Zamora (channel linked below), who many of you know has long-studied the Carolina Bays, proposing a hypothesis for their geomorphology that relates to the proposed Younger Dryas impact.
On looking at the Y-Chromosome data, Zamora notes the peak in males coincides with the beginning of the Younger Dryas, but then we see a small dip and then a rapid decrease in numbers. Therefore, could the Younger Dryas have caused the Y-Chromosome bottleneck? Is this scientifically feasible?
In this video I take a look at the science and the data and give my own personal opinion on whether or not the Younger Dryas cooling could have been the cause of the lack of male diversity in the global human population.
