Female Excellence in Rock Climbing Likely Has an Evolutionary Origin

Abstract

AbstractThe human body is exceptional for many reasons, not the least of which is the wide variety of movements it is capable of executing. Because our species is able to execute so many discrete activities, researchers often disagree on which were the movements most essential to the evolution of our species. This paper continues a recently introduced analysis, that the performance gap between female and male athletes narrows in sports which most reflect movements humans evolved to do. Here, I examine the performance gap in rock climbing. Because rock climbing is so similar to tree climbing, which bountiful evidence suggests has been key to the origin and proliferation of our species, we would expect to see a narrow performance gap between men and women in the sport. Indeed, this is the case. Female climbers are some of the best in the world irrespective of gender, a trend that is not found in any other major sport. I conclude that exceptional ability of female climbers is further evidence of the existence of sex-blind musculoskeletal adaptations, which developed over the course of human evolution to facilitate essential movements. These adaptations abate the general physical sexual dimorphism which exists in humans. This paper provides more evidence that the performance gap in sport can be used as a measure of human evolution.
