A Single Gene Mutation May Have Helped Humans Become Optimal Long-Distance Runners
Health & BehaviorTwo to three million years ago, the functional loss of a single gene triggered a series of changes in what would eventually become the modern human species. Researchers at University of California San Diego School of Medicine report on studies of mice engineered to lack the same gene and resulting data that suggest the lost gene may also have contributed to humanity’s well-documented claim to be among the best long-distance runners in the animal kingdom.
