Matriarchal extermination of 95% of human males in the late neolithic

https://news.stanford.edu/press-releases/2018/05/30/war-clan-structubiological-event/ The male gene pool apparently collapsed about 7000 years ago. Either only a very small proportion of the male gene pool expanded dramatically, or almost 95% of males were exterminated systematically, and women outnumbered men 20 to 1, for a period of about 2000 years. I favor the latter explanation. Women were the first farmers, as an extension of their "gathering" function in paleolithic hunter-gatherer societies. So, female priestesses and Queens would have acquired great power, as the traditional hunting function of men in paleolithic societies became less critical, and female dominated farming became more important. Indeed, the aggressiveness, predatory sexual behavior and social non-conformity of men, as a gender, may have been perceived as a threat to the peaceful order of neolithic agricultural societies by the late neolithic. Hence, a simple solution was arrived at. Systematic infanticide of the vast majority of male human births, probably by exposure. No trace of these soft-boned infants would likely remain, all consumed by wild beasts. Of course, the contraction of the gene pool would result in reduced genetic diversity and the diseases and malformations typical of all inbred societies. Hence, in time, these matriarchies were perceived as being accursed, by the Gods, and they were overthrown, and replaced by the patriarchies typical of historic times, by 5000 years ago.
