A new study conducted by researchers at Durham University has found that women who are taller and slimmer are giving birth to more babies thanks to improved healthcare and nutrition.
The researchers made use of the data collected by UK Medical Research Council between 1956 and 2010 in two Gambian villages. The researchers also recorded the mortality and fertility rates among the communities and found that improved nutrition and medical care led to significant shift from low mortality and fertility rates to high rates.
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.
The study has been published in the journal Current Biology.
