Scientists have figured out why our men exist

A non-sexual reproductive system, without men and without sex seems like a much more efficient path. But why do people choose the path like now?

Find out why men exist

Thought is a meaningless question, but the reason why men have existed for so long has made scientists extremely confused. They argue that sex division of species and sexual reproduction are costly and inefficient processes. Yet the majority of multicellular animals choose this form to maintain the race.

Until recently, it seemed the final knot of the question 'Why do men exist?' recently removed by a team from the University of East Anglia (UAE). Accordingly, scientists propose the cause comes from the process of 'sex selection' . It plays an important role in improving population health and avoiding the risk of extinction.

Having men and sexual reproduction are expensive and inefficient processes.

The new study, published in Nature, uses Tribolium, a beetle species to explain why most multicellular animals choose to have sex to reproduce. For 10 years, they followed the development of 50 generations of laboratory beetles with a tightly controlled environment. The effects of sex selection, the process of male competition to gain the choice of females, have been carefully monitored.

'Almost all multicellular animals choose to use sex to reproduce. However, the existence of this is not easy to explain, said Professor Matt Gage from the Department of Biology at the University of East Anglia.

'We want to understand how Darwin's theory allows this wasteful, popular reproductive system to exist. While, a non-sexual reproductive system, without males and without sex, seems to be a much more efficient path , 'he added.

Tribolium, animals help answer the question of why men exist.

Finally, by observing the Tribolium, the team found that if the sex selection process is removed, the beetles are not competing to gain partners, the health of the entire population. will decrease quickly. After only 10 generations, they will become extinct. Conversely, when the environment is more intense, 90 males compete to get 10 females, the risk of extinction is markedly reduced.

'In order to compete and attract partners, males must have good qualities. Therefore, sex selection is an important filter for these qualities, helping to maintain and improve the genetic health of the population , 'Gage said.

Thus, in short, sex selection is the final answer to why men and males in multicellular animals exist. It is a filter for harmful genes and leaves good genes. Women or females will be less likely to mate with males carrying bad genes. This promotes a healthier population and reduces the risk of extinction.
