A team of scientists from the University of Stirling in Scotland has uncovered the mystery of the existence of sex in nature. Previously, one could only guess about why living beings on the planet needed a complex system for reproduction with a search for a heterosexual partner, while some organisms safely manage asexual reproduction, spending much less time and energy on it.

For their research, British scientists used planktonic crustaceans Daphnia, whose females, depending on conditions, can reproduce both sexually and asexually. They use the latter option when the environment deteriorates. As a result of the experiment, the researchers were convinced that the offspring of the female and male daphnia received more perfect immunity from them than the offspring from the female alone. Similar conclusions at the University of Stirling are ready to extend to people.

“It would seem that while the males are fighting for the female, self-breeding creatures could dominate, but for some reason we are not surrounded by clones. Comparing the offspring of Daphnia from the same females, we found that individuals born as a result of sexual intercourse are less sick than those who have been cloned. The need to resist disease explains why sex persists in nature, despite the cost, "- quoted by the BBC, Dr. Stuart Auld from the Faculty of Science.

Thanks to this feature, sexual reproduction began to dominate the planet. Komodo monitor lizards, starfish, bananas and other organisms that reproduce without the need for the participation of a partner, nature has identified as outsiders, not to mention those who have not survived to this day. Genetic uniformity did not allow them to properly adapt to changes in the environment.

Previously, psychologists from the University of Toronto proved that the happiest couples have sex only once a week, thereby refuting popular ideas about frequent sex as the basis of relationships between a man and a woman.
