In addition, men gained an average of 6. 48 kilograms (14. 29 pounds) and women gained an average of 2. 70 kilograms (5. 95 pounds).

“This is one of the first studies to make a connection between the evolution of humankind as driven by sexual selection in combination with the effects of environment on ultimately our phenotype, so how we ultimately present ourselves, how we ultimately look characteristically,” Halsey told CNN on Wednesday.
In the past, taller, heavier men would tend to be stronger, enabling them to outcompete other men, gaining more access to women and passing on their tall genes, he said.
However, even today, “women tend to prefer taller men,” he said, while, “in contrast, women’s height isn’t so important. So, to put it simply, men don’t tend to say, ‘Oh, I only like tall women.’”
