New analysis of human genetic history reveals female dominance

Female populations have been larger than male populations throughout human history, according to research published today in the open access journal Investigative Genetics. The research used a new technique to obtain higher quality paternal genetic information to analyze the demographic history of males and females in worldwide populations.

The study compared the paternally-inherited Y chromosome (NRY) with maternally inherited mitochondrial DNA (mtDNA) of 623 males from 51 populations. The analysis showed that female populations were larger before the out-of-Africa migration and remained so throughout almost all subsequent migrations. The main drivers of this trend are likely to be processes such as polygyny, where one male mates with many females, and the fact that in most societies, women tend to move to live with their husbands. This has resulted in females making a greater genetic contribution to the global population than males.

  1. I think of the many misogynistic males throughout history who gloat that they were so much more superior than women.

    The truth of the matter lies on their own chests: male nipples!.

      1. Apparently males were formed from the female body which is why men have nipples. The y-chromosome is an aberration, a genetic defect that, as was reported here earlier, is loosing most of its genes as the millennia roll onward.

        1. I used to watch a program call Creation Magazine.

          – Adam and Eve’s first few generations of offspring should not have been getting married so how did they reproduce? Brothers and sisters could reproduce back then because the genes were not “sinful” until later.

          – The Ark could only carry so many different types of living things, so how did we get so many varieties today? Noah only took the living organisms that contained all the needed DNA/genes. After he landed, the different species “mutated” (evolved) in the millions of different kinds of life we see today.

          Who needs those damn science books when we got the Bible?

  2. Opinions on abortion are like nipples, everyone has them but women’s are a little bit more relevant. But all you ever see are men’s.
