Humans are still changing, and the female winners of the evolutionary crapshoot will be shorter and heavier down the line. A new study that tracked the motherly productivity of the slim-and-tall set alongside their squatter peers concludes that a lower center of gravity will win out in the end, and it offers a surprising prediction: By 2409, women will be on average almost an inch shorter and 2 pounds heavier.
Still think evolution isn’t working on us humans? “That’s just plain false,” the study’s lead author says. Another finding: women who give birth earlier or enter menopause later appear to pass those traits along to their daughters. As a result, researchers think that women will eventually produce babies at a younger age than they do now, by 5 months or so on average, and enter menopause 10 months later, notes the Telegraph.
