The nature of homosexuality partially explains the evolutionary genetics15 октября, 2021
On the one hand, it is a paradox, because representatives of the same sex, as a rule, rarely become biological parents. On the other hand, the new work of Australian scientists shows that similar genetic patterns are often present in people with heterosexual orientation, but with a small reservation.
The genetic nature of homosexual behavior seems to be the genetic nature of homosexual behavior, since its representatives, both people and animals, do not produce a large number of offspring, thereby the transfer of genes that predispose to homosexuality should be rare.
In fact, there are similar genetic patterns in heterosexual people. On research conclusions
To come to this conclusion, scientists analyzed the genomas of 477 thousand people who had at least one sexual experience with a representative of their sex, and then compared data with genomes of 358 thousand people with heterosexual behavior. In addition, they simulated evolution for 60 generations to trace the characteristic patterns.
It turned out that many genetic versions associated with homosexual behavior would disappear over time if they did not help people survive and reproduce offspring.
Scientists have established that people with homosexual behavior share common genetic biomarkers with people with heterosexual behavior, which characterized themselves «prone to risk.» The latter had more sexual contacts with representatives of the opposite sex and more children. From the towers of evolution, it becomes clear why the preservation of these genetic patterns was maintained, scholars were concluded.
