People are still evolving

The natural dynamics of evolution continues the process of cutting humanity, even though we are proud to have the power to intervene and transform the world around us.

Evolution takes place in response to external influences, eliminating which individuals are less able to cope with those pressures, allowing more suitable individuals to survive and thrive. However, since humanity has strongly interfered with the habitat, will those natural selection dynamics continue to affect humanity? Modern agriculture, for example, can produce an abundance of food, eliminating the risk of starvation in many parts of the world.

The new discovery, published in the Proceedings of the National Academy of Sciences , adds evidence that evolution is still ongoing. Research by the University of Wisconsin used to suggest that the human brain is shrinking in the past 5,000 years. Another study, experts from the University of Sheffield (UK) reviewed the genealogy of nearly 6,000 Finnish people from 1760 to 1849, with full information such as birth date, death date, marriage and background. economy. Next, they investigated the impact of agriculture on four aspects of human life: survival to adulthood, access to partners, successful pairing and fertility rates for each. work.

The results showed that the subjects in the study continued to evolve as other species in the wild. More surprisingly, both the rich and the poor face similar natural choices, according to Alexandre Courtiol expert of the Advanced Research Institute in Berlin."Many people think that wealth can protect them from the effects of the environment, but in reality it is not," Courtiol said. Rich or poor have to undergo the same period of survival and reproduction. And in most species, nature also has discrimination against two sects. The male pairing ability evolved faster than females, as evidenced by the fact that men quickly remarried compared to females, according to Courtiol.

Thus, in fact, the natural selection process continues to take place in humans despite changes in agriculture and cultural changes, which scientists have not appreciated properly in the past.
