Why can't humanity lack men?

Scientists have finally figured out why sexual reproduction continues to exist despite the asexual reproduction of the female whole in some animals. This finding also helps explain why men exist in the world.

Explain why mankind is indispensable for men

While most men will claim that they play a central role in human development, in some animals, the presence of males is less important. However, scientists now discover that males have a special role: to ensure competition for females, to help a species grow healthy.

In many animals, male individuals do not support parenting and often only provide sperm needed for egg fertilization . The natural selection process, which eliminates inefficiencies in the natural world, inevitably leads to the process of mating without mating , as more and more individuals are born in this way.

Some snails, insects, reptiles and sharks can reproduce the whole female or reproduce mono, in which an embryo develops from an unfertilized egg. However, in the new study, scientists learned why this reproductive form is still relatively rare in the animal kingdom.

Professor Matt Gage, head of research at the University of East Anglia (UK), explains: " Most multicellular species on Earth reproduce through mating, but the existence of this form is not easy to reason. Sex carries big burdens, but it is clear that only half of the females are born - female individuals - will actually give birth to babies, why don't any species remove all the males?

Competition for reproduction in male individuals provides a really important benefit, as it improves the genetic quality of the species. The sex selection process achieves this by acting as a filter to remove harmful genetic mutations, help communities to thrive and avoid long-term extinction. "

In many animals, the process of sex selection leads to intense competition and often also involves violence between males. For example, the stag will have to fight with each other to gain the right to mate with a female, while the male paradise birds will perform colorful dances to seduce the children.

To win such competitions, males must be stronger and often bigger than their peers, meaning they need to possess good genes to do so. By transmitting these genes to their children, they will help ensure their health and long-term survival.

Professor Gage stressed, without mating , unhealthy genes will continue to be transmitted to later generations, causing degeneration of the race.
