A new study has found that women who are taller and slimmer are giving birth to more babies thanks to improved healthcare and nutrition.

On analyzing the fertility rates, along with height and weight, and found that while natural selection initially favored short and heavier women, it has now favored tall women with a lower body weight.
“This is a reminder that declines in mortality rates do not necessarily mean that evolution stops, but that it changes. Our results are important because the majority of human populations have either recently undergone, or are currently undergoing, a demographic transition from high to low fertility and mortality rates”, Dr Ian Rickard said.
The study has been published in the journal Current Biology.
