We know the saying that sounds in French In Papyrus, the ápádo becomes an outdated democracy? Then we know that in Hungarian it means A priest sits on the bench, hair on his legs, worn out, but growing. It’s a woman, but not for long, because for some mysterious reason, men almost don’t have body hair anymore — although estheticians have a word or two for that. That little tuft of short-haired fur, which some men still flaunt—and since they really do depilate, there aren’t many of them—is ridiculous in the eyes of a bear or an orangutan, and they can scratch their heads as they wonder: What is this ‘thing’ ” Little?
It has become old fashioned
Wearing fur is characteristic of mammals, it was a serious trend among the ancients, but then it went out of fashion with us, simply because we did not need it. But humans aren’t the only species losing their woolly fur. 62 different mammalian species, approximately 20,000 encoding genes and 350,000 regulatory genes Analyze it Geneticist Amanda Kowalczyk and her team have identified a mechanism for the origin of this peculiarity.
If evolution makes hair redundant, the genes that affect it become secondary, and the body does not produce the type of hair it used to.
In the case of mammals, hair loss can be traced back to a variety of causes. In the case of elephants, for example, the heat weakened them, in the case of walruses, the faster movement of the water made that unwarranted. Behind the disappearance of human hair, on the one hand, is redundancy: the role of thermoregulation has been taken over by clothing over time, and on the other hand, the number of parasites has also decreased with the disappearance of hair.
Sarah Millar, MD, clinical professor of dermatology at the University of Pennsylvania School of Medicine to me
One of the practical reasons for hair loss is that if the most useful parts of our body, such as the hands, are hair, it is difficult to grasp things, which is why our ancestors lost the hair of their palms and wrists.
Crazy theories
The water monkey theory suggests that our ancestors who lived in the African savanna hunted and gathered, and in the dry season they moved to the shores of lakes and waters and searched for tubers and water shells, but the fur is not a good insulator in the water, so we threw our fur and instead grew a layer of fat.
According to the theory of thermoregulation, when Neanderthals moved from the forests to the savannah, hair became redundant in the heat of the day, the number of sweat glands increased, and clothing appeared, representing protection from the sun and cold.
Mark Pagel, an evolutionary researcher at the University of Reading Sayshair with an important function of sun protection was preserved, pubic hair was preserved due to the storage of pheromones, but hair covers the rest of the body Poetry Losing it was practically against parasites and other parasites hiding in the hair.
One of the most interesting theories is that facial hair and pubic hair help with emotional communication. According to developmental neurobiologist Mark Changizi, we communicate non-verbally by changing the oxygen supply to the face, that is, its color. Green or blue skin can indicate illness, a red cheek can indicate affection, and a red face can indicate anger. But of course, we can only see these colors if our face is not covered with hair.
But do not think that if it were necessary, our bodies would never again be covered with rich and silky fur: the gene responsible for the formation of fur is still in our DNA and can jump out at any time. Perhaps it would be a good idea to start putting the spruce slices in with the flour and milk, though if all felt, it was not worth it to remove them.
