What are the male males
The scientists decided to answer the question – why do we need men in nature -samtsy. It appears in the animal world and people are interconnected and males not only play the role of reproduction as selection. According to a report published in the journal Nature, the sexual selection plays a critical role in the evolution of species.
In order to establish the truth the British implemented a large-scale experiment. As part of the set of tests on beetles, biologists discovered that males are not limited to performing the function of fertilization of female representatives, but also to support the vitality of the entire population. The latter occurs by preserving genetic health of a new generation.
The essence of the experiments was to decrease and increase in the frequency of sexual selection of representatives flour beetles. The number of females was 10 and men at 90. This mating females choose the most appropriate – “discarded” weak.
As a result, in the fiftieth generation developed the most “genetically” healthy offspring. It is worth emphasizing that the larger males had better genetics forms the offspring. As a result, competition for mating survival of the fittest members of the species.
According to Professor Gage, the system of sexual selection provides a strong spread of genes and prevents the growth of bad genes, so that the element of struggle among males provides improved genetic health of the population. And in order to attract the right females, males have to fight and only if they are victorious in a serious fight, they have access to the right female.
In this selection of human life continues to exist, though not so bright. That the owners of strong genes achieve good results at work and were victorious for the attention of girls, so the male males still continue to govern natural selection.
