A new study in the journal Investigative Genetics shows that, throughout human history, more women were reproducing than men were.


The study examined DNA samples of people from around the world, looking into their mitochondria DNA (mtDNA) passed down through the female line and at the y-chromosone passed down through the male line.

The researchers found that historically, more women than men were reproducing, potentially as a result of polygyny (in which one man is married to multiple wives). But the results also showed geographical differences, as LiveScience reports:


On a regional scale, the DNA samples showed a detailed story. For example, people in East Asia and Europe have larger genetic differences for paternal than for maternal DNA, suggesting high levels of female migration. In contrast, populations in Africa, Oceania and the Americas have bigger differences for maternal DNA than for paternal DNA.
Perhaps fewer men than women reproduced among America's early colonists, the researchers said when they saw the high amount of mitochondrial DNA diversity.

Mitochondrial DNA is useful for all sorts of historical explorations; it has also, recently, been one of the key components in the identification of Richard III, whose body was found buried in a parking lot in 2012., and in the newest evidence for the real identity of Jack the Ripper.

In nature only the top males ever reproduce.

In our world we had tried to mitigate against that by making marriage basically mandatory and allowing for only one man and one woman to be together.

Since that model is being thrown in the bushes these days, the natural system is kicking back in.

20% of the males get 80% of the females.

I know for sure cause I used to be the top 20 (I guess.. never had any droughts before recently) now I'm in the bottom 80 (cause women have stopped throwing themselves at me).

That is categorically false.

The males most willing and capable to provide for their mates and offspring are.

This is why monogamy was 'created' by our simian ancestors millenia ago and enabled homo sapiens to dominate the planet.​

Read the OP:

also:

We also find that the ratio of female effective population size to male effective population size (Nf/Nm) has been greater than one throughout the history of modern humans, and has recently increased due to faster growth in Nf than Nm.
