Scientists have proven the need for men
English researchers conducted a study to find out what nature has created a strong half of the population. It turns out that the representatives of the stronger sex is necessary not only for posterity, but also for the recovery of the population.

Professionals from the Institute of Eastern Britain asked a question about why nature is made up of representatives of the stronger sex, if their role is only to procreate, informs The Daily Mail. Considering the opinion of the researchers, sex excessively energy-consuming for the inhabitants of our planet lesson, which among other things can lead to the birth of a boy. Along with this many species of insects, reptiles and even sharks ready to be pregnant.

"Sex brings large overload, the more so as a result only half of your children - girls - are to produce offspring. Why should people spend so much effort on sons?" - asks questions to the Manager of the research group, Dr. Matt gage.

To find the answer to this question, researchers for 10 years been cultivated in the laboratory flour beetles and followed their evolution. Test subjects broke into several groups, each of which changed the intensity of sexual selection during the reproductive period. For example, in one group the male can mate with only one female in the other 10 individuals of the fairer sex had chosen a mate from 90 males. Bearing in mind that flour beetle monogamous, the females had to select the best for the continuation of their kind. Thus, experts have traced for the genetic health of more than 50 generations of insects. The results of the study showed that the better was sexual selection among males, the stronger and healthier the population. In a group where females was virtually nobody to choose from, beetles grew frail and sick. Professionals suffered acquired findings on the human race.

Men need to be strong and healthy to win in the competitive struggle with each other for the right to enter into a sexual relationship with a lady. "In the absence of sex in the population accumulates harmful mutations, and sexual selection helps to offset them, allowing the population to protect themselves from extinction," concluded Dr. gage. Therefore, nature intended men to maintain healthy offspring.
