What is the purpose of the armpits?

Although some have signed up for creationist beliefs, it is quite common scientific belief that homo sapiens evolved from earlier homonides that had a lot of hair hair, not only in their armpits and hair, but all over every thumb of the skin. For many millennia, it seems that less and less hair is the way the natural selection has taken, although some believe that the hair that remains serves for some purposes. It is assumed that the hair of the armpits, not only brings up a heated, musty nest of pheromones attracting Mate, but also offers protection from glittering. However, it seems that women who regularly shave their armpits and other regions do not mind his absence.

Although this can be easily considered a assumption, some scientists believe that the hair of the armpits was still part of the human package mostly due to pheromones. The apocrine glands of the armpits are the main producer of these secretions, which many animals and people emit to attract friends. More hair present has for the aftermathDEK more of environment rich in proteins for chemical communication through pheromones. In fact, they are bacteria of armpit hair that break down sweat into something stinking, because the pheromones are considered odorless.

Several manufacturers of perfumes and Cologne Cologne claim to include human pheromones in their recipes to provide attraction. Some scientists question whether these odorless hormones can be distilled and reported that many of these mixtures contain synthetic versions of natural hormones of the body. Regardless of the debate on the attraction of the smell, some speculate that the hair -rich hair -rich armpit is useful for reducing the amount of friction that produces between the upper arm and the torso during movement. Others, however, insist that the bristle hair actually adds friction and do not provide any lubrication at all.

scientists began suspicion and investigation of the existence of hormonal pheromones beforefor more than 100 years. Only in 1959, however, was named as two scientists, Swiss entomologist Martin Luscher and German chemist Peter Karlson. The word "pheremone" means "carrier of excitement" in Greek. However, the discovery was created with thermit instead of people and their hair from the armpits.

According to the National Academy of Sciences, Pheromone research has largely focused on the attraction of insects, especially in the field of pest management than on the content of the pheromone of human armpits. For example, in 1980, the pheromones were lured by 4,000,000,000 beetles on a trap in Norway and Sweden to stop the infestation that threatened crops. This technology has spread all over the world, although understanding human pheromones is largely elusive in 2011.
