Women evolving to be shorter, heavier says research from UK Telegraph reports on research from Dr. Stephen Stearns at Yale University indicate that genetic studies indicate women will evolve to be shorter and heavier down the line.
It found that shorter, heavier women had more children than lighter, taller ones. Women with lower blood pressure and cholesterol were also more likely to have large families.
Women who gave birth early or had a late menopause were likely to have more children as well.
More importantly, however, these traits were then passed on to their daughters, who also, on average, had more children.
The study has not determined why these factors are linked to reproductive success, but it is likely that they indicate genetic, rather than environmental, effects. Prof Stearns’ team controlled for other factors, including social and cultural change.
