why in both genders hairs grow in pubic area and underarms only?

Answer 1

Humans no longer have noticeable body hair because we no longer need it either to keep us warm or to shield us from the sun. Elaine Morgan in her book The Descent of Woman suggested that we lost our body-hair during an aquatic period in human history.

We still have hair under our armpits and around our genitals probably because these are areas where pheromones collect. Humans still attract each other pheromonally and the smell of axial hair is important in this. (This is why girls with hairy armpits are always sexier).

Though it is more difficult to know why we have kept the long hair on our head.

Answer 2

There is no definitive theory on the reason for the existence of pubic hair. The prevailing theory relates to pheromones — scents that the body produces that can be sexually stimulating to others. In this theory, the tufts of hair that grow around the genitals, as well as under the arms, capture these ****** scents. Pheromones get trapped in the pubic hair when apocrine glands release an odorless secretion on the surface of the skin that combines with bacteria decomposed by the secretions of the sebaceous glands. Humans have the same number of hair follicles as gorillas, chimpanzees and orangutans, but body hair is generally very fine or barely visible in comparison. So, while pubic hair and underarm hair might be considered the primary scent traps, they are not the only ones. For some people, scents from these areas are noticeable and consciously increase sexual arousal. Pheromones might not be obvious but may be detected subconsciously.

Another theory is that the pubic hair keeps the genitals warm. The purpose of women's pubic hair could be similar to that of the cilia in the nose, in that it prevents small foreign particles from entering the vagina. However, this doesn't explain male pubic hair.

Answer 3

Our whole body has grown hairs. There is a specific area that is visible especially in pubic area and underarms, there purpose is to protect from frictions.

Answer 4

hair doesn't grow only in the pubic area and underarm area . we have hair on our whole body , only that it's not that easy to notice . it's all about evolution , we have lost our hair because we don't need it anymore to protect us from cold .

Answer 5

It is your belief that the hair only grows in these two regions of the body however the entire body is capable of this hair growth exception palms of hands, bottom of feet, eyelids. The amount of growth is dependent on release of follicle stimulating hormone in the system many people don't experience the release of this hormone in rapid release but over periods of years i.e. chest hair!
