Men with higher endurance level are also more attractive, says a new study. It also links these two qualities with Darwin's natural selection process.
On the basis of this theory, sportsmen are more handsome, scientists said, adding that females are more attracted towards physically fit men.
Erik Postma, a professor of evolutionary biology at University of Zurich, selected 800 participants for his study. He used photos of 80 Tour de France racers' heads and shoulders and then asked the participants to judge their attractiveness. It was found that those cyclists who fared the best in the race also grabbed 5 per cent better grade for attractiveness.
Dr Postma said, "Individuals with higher endurance capacity were likely to be better resource providers for their partner and progeny. And across cultures, women place a lot value on the provisioning ability of their prospective partner."
According to the study published in journal Biology Letters, choosy women prefer to have sex with high quality males as they make "good fathers" and provide "good genes" for their offspring and one important parameter to decide this is physical performance.
Women who found the winners to be more attractive were also the ones who were not using hormonal contraceptive.
Thus, the study claims that handsome men stand first.
