Hungry Moms Produce More Girls

It’s amazing how animals and humans adapt to changing environmental conditions. Evolution has apparently built in the propensity for animals and humans to spawn more females during food shortages:

Overall, the ratio of boys to girls born dropped to 0.88. Sons require more reproductive effort than daughters. “They grow a bit faster, they’re bigger when they’re born,” Mace says. Males are also less likely to survive if malnourished as children, and stunted males are less attractive as potential mates.

So the girls are easier to raise during troubled times. I’ll vouch for that :)
