Genetics are weird and interesting!!

After an extensive talk with a wonderful confidant of mine, I have concluded that “Neat!” is not an appropriate response to an earnest confession of emotions.

Today's Men Carry Traces of Ancient Wars in Their Genes

Modern men’s genes suggest that something peculiar happened 5,000 to 7,000 years ago: Most of the male population across Asia, Europe and Africa seems to have died off, leaving behind just one man for every 17 women.

This so-called population “bottleneck” was first proposed in 2015, and since then, researchers have been trying to figure out what could’ve caused it. One hypothesis held that the drop-off in the male population occurred due to ecological or climatic factors that mainly affected male offspring, while another idea suggested that the die-off happened because some males had more power in society, and thus produced more children.

Now, a new paper, published May 25 in the journal Nature Communications, offers yet another explanation: People living in patrilineal clans (consisting of males from the same descent) might have fought with each other, wiping out entire male lineages at a time. Read more.

I could find uses for this! and it’s strange and really neat!!!
