Researchers Tim Clutton - Brock and Kavita Isvaran of the University of Cambridge in the UK conducted a survey of 20 different vertebrates, with the result that the larger the size of polygamy, the shorter the life span of the male than the female It is said that. According to the researchers, as the competition of male mating increases, the number of matings per male decreases, so male of such species loses strong motivation to evolve to longevity, has a short life span I will explain.

According to Clutton - Brock, humans seem to think that the longevity of men has been shorter than that of women since the late stone age where polygamy was common.

It seems that the era when polygamous polygamy system of mankind was normal was longer than understanding with general feeling.
