It is known that the Pets appear more attractive than the wild. But can we say the same about people? Researchers believe that the answer to this question lies in the mutation of certain genes. A recent study showed that the attractiveness of domestic animals and human persons as we know them, have established as a result of genetic mutation. Some scientists believe that members of our species successfully domesticated not only animals, but also themselves. According to this hypothesis, the domestication of people there for many generations. As a result of aggressive Homo Sapiens lost to friendly and cooperative people. Not surprisingly, this behavior has resulted in other genetic changes which humans, like other domesticated animals, externally, have become very different from their ancestors.
How did the domestication of Homo Sapiens?
In the course of the domestication of animals, people adhered more or less uniform requirements and all the animals were varied in a similar way. Large specimens have become smaller, the differences between the sexes were smoothed out, changed the color and kept the “kids” signs like drooping ears. Changes are not spared and the nervous system: the animals became more docile and less aggressive. Subsequently, however, the researchers found that the wild species in appearance and their behavior began to resemble domesticated. So, Bonobo monkey today are more like domesticated chimpanzee — they are less aggressive and peaceful, but puberty is longer. But could the same thing happen with humans?
In 2018, researchers from the University of Barcelona published work, according to the results of which were discovered the genes responsible for the domestication of man. In the study, a team of scientists compared the genes of Homo Sapiens, Neanderthals and Denisovsky people. So I have compiled a list of genes that were differently presented to us and our ancestors. Similar lists were later compiled for cows, Buffalo, dogs and wolves.

In the course of work on the study, which was published in the journal PLOS One, the experts have found similarities between certain genes in both animals and humans. To verify the reliability of the results, the researchers conducted a comparison of “domesticated” genes of cows and dogs with the genes of orangutans, gorillas and chimpanzees. It turned out that today some options for the “domesticated” genes found in nearly every human, while has not been discovered or prevalent in the DNA of Neanderthals and Denisovsky people. These genes are responsible for changing human faces in the course of evolution. In General, the researchers came to the conclusion that they have found evidence of domestication of the person. Also the authors claim that the obtained results are consistent with theories of how in the course of evolution, humans and Pets become more friendly. However, to the hypothesis of domestication of a man turned into a theory more research is needed. However, despite the criticism of published work, thanks to the obtained results the scientists know what genetic features in the future need to pay attention.
