Why Males Die Before Females | LiveScience
In humans and many other animals, males age faster and die earlier than females.
New research suggests this might happen because of intense competition over sex.
After investigating about 20 different vertebrate species, researchers Tim Clutton-Brock and Kavita Isvaran at the University of Cambridge in England found the more polygynous a species was, the more likely their males were to age faster and die earlier than females.
The researchers explained that as competition among males for sex grows more intense, each male on average has less time to breed. As such, there is no strong incentive to evolve longevity among males in such species.
See ladies, we can’t help ourselves. —-It’s genetic.
