London : Males with greater “reproductive potential” from an evolutionary standpoint are better distance runners and females chose for such athletic endurance while mating in the past, says a research, reports IANS.
Using finger length as a marker for hormone exposure, the latest research on marathon runners showed that people who experienced higher testosterone in the womb are also better at distance running.
“The observation that endurance running ability is connected to reproductive potential in men suggests that women in our hunter-gatherer past were able to observe running as a signal for a good breeding partner,” said study’s lead author Danny Longman from Cambridge University.
Researchers said females might have selected for such athletic endurance when mating during our hunter-gatherer past, perhaps because ‘persistence hunting’ — exhausting prey by tirelessly tracking it — was a vital way to get food.
“It was thought that a better hunter would have got more meat, had a healthier and larger family as a consequence of providing more meat for his family. “But hunter-gatherers may have used egalitarian systems with equal meat distribution as we see in remaining tribes today.
“In which case more meat is not a factor, but the ability to get meat would signal underlying traits of athletic endurance, as well as intelligence — to track and outwit prey — and generosity to contribute to tribal society. “All traits you want passed on to your children,” Longman explained.
