Isn't something like 80% of our genetic DNA descended from women - i.e. every woman has reproduced but only a handful of men have?
Seems like this woman is just wanting to go back to the Stone Age.
Do you have a source for this?
I have a different
one (which I believe I've posted here before), but it conveys the same idea:
Quote:Quote:
...ρX/ρA reflects the female-to-male breeding ratio, β. We estimated β from ρX/ρA inferred from genomic diversity data and calibrated with recombination rates derived from pedigree data. For the HapMap populations, we obtained β of 1.4 in the Yoruba from West Africa, 1.3 in Europeans, and 1.1 in East Asian samples.
Two takeaways here:
1. Indeed, humans have been polygynous throughout history and prehistory, with more women than men contributing to future lineages (i.e., it's more winner-take-all on the male end.)
2. Unsurprisingly, populations with higher historical female-to-male breeding ratios are the populations that have lower rates of paternal investment today, and vice versa. Also unsurprisingly, low rates of paternal investment are associated with low socioeconomic productivity and high crime rates both across and within nations.
It is not so clear whether, or to what degree, low paternal investment across societies and within societies
causes low productivity and high crime, or whether the traits that lead to low paternal investment and low productivity and high crime are just frequently concurrent. I suspect it's more of the latter than the former, as various studies have shown that parenting
per se has little effect in long run child outcomes, compared to genetics and environment, in that order.
Either way, regardless of the nature of the causality, if you want a productive society with low crime, you want the dads outbreeding the cads and the women who prefer dads to outbreed the women who prefer cads.
I, for one, will continue cadding around while rooting for the dads to beat out the cads. Hypocritical? Nope, merely the prisoner's dilemma and the fallacy of composition.
