Israeli scientists think they know why men and women constantly bicker over heating control or air conditioning settings: evolution.
They observed that just as females tend to be colder than males, other species are divided according to temperature – and have monitored 40 years of records on the behavior of bats and birds in Israel. .
The result is a theory, recently peer-reviewed and published in an academic journal, suggesting that species have the best chance of surviving when males and females keep their distance from each other.
“We suggest that different temperature preferences reflect differences in the nervous system, and that just as men and women experience pain differently, they experience hot and cold differently,” lead author told The Times, Dr. Eran Levin of the School of Zoology, Tel Aviv University. from Israel. “And because of that, they often stay separate from each other, looking for different temperatures.
“This is more common in birds and bats, for example, you tend to find male bats that go to higher elevations at the top of the mountain while the females are in the valleys where the temperature is higher.
“Much has been written about males and females of various species living separately, but the explanations varied from species to species. We observed a clear trend in birds and bats, explained by temperatures, and in mice, males live in cooler places than females. Our theory suggests that these and other species perceive temperature differently, guided by natural selection.

Levin, who has collaborated with researchers at the University of Haifa and Tel Aviv’s Sourasky Medical Center, said it has proven to be “very beneficial” in terms of evolution, adding: “It’s because, with birds and bats, this causes gender separation. outside of the breeding season, which reduces competition between males over females. It reduces the aggressiveness caused by competition for women between men and reduces aggression towards women and their children.
There is another benefit in women who feel cold more, he said. Females tend to take care of their offspring, which in many cases needs the temperature regulated for them. When females are more sensitive to the cold, they have a greater incentive to warm the young, Levin said.
Levin’s colleague Dr Tali Magory Cohen said the evolutionary push is the same in humans – to give men and women space from each other.
“At the end of the day, going back to the human realm, we can say that this difference in thermal sensation did not happen so that we could discuss with our partners about air conditioning, but rather the opposite,” he said. she declared.

“This is to keep the couple away from each other so that each individual can enjoy a little peace and quiet,” she continued.
“The phenomenon can also be linked to sociological phenomena observed in many animals and even in humans, in a mixed environment of females and males: females tend to have much more physical contact with each other, while males keep more distance and avoid contact with each other. “
