Breasts come in different shapes and sizes. But the many options have in common is this trait unique to humans. Despite the fact that our world is home to over 5,000 species of mammals, Homo sapiens is the only form of life with a strong chest.
Human anomaly, especially if we’re talking about women, is considered sexy. And so it is. However, the question of why human Breasts are so big and if this was actually an evolutionary error remains open.
Why women’s Breasts
Every mammal that it resembles IFL Science, is developing a “temporary” Breasts during ovulation or breast feeding to produce milk. As soon As the milk disappears, disappears and the chest. But, as we all know, does not apply to women who have breast appears during puberty, not pregnancy, and stays with them for life. Why?
Perhaps the most popular theory was first proposed by Charles Darwin, and then examined by the zoologist Desmond Morris (Desmond Morris) in the book “the Naked APE”. In it, Morris suggests that Breasts evolved as a sex symbol, designed to replace swelling during ovulation the buttocks of a female primates. When our ancestors became bipedal, these bodies were no longer so obvious. Thus, men had no way to know a woman is sexually Mature or not.
This theory, say modern scientists, explains not only the presence of Breasts, but also her emergence into puberty (and also swelling as part of initiation). Although, to be fair, can’t explain why the Breasts is still a woman in postmenopause.
The main difference between a woman’s Breasts and the Breasts of a female mammal in this case is that the former contains much more fat. That fat fills out breast tissue, giving it an attractive shape. And Yes, that’s the reason Breasts are getting smaller, when a woman loses weight.
The phantom menace of the female breast
Speaking of breast, we could not tell you about breast cancer — one of the most common types of cancer, annually damaging about 1.5 million women.
Scientists say that breast cancer is not common among other primates. What, in their opinion, may be due to the fact that the risk of disease increases with age, and other primates just don’t live long enough to get it.
There is also an opinion that breast cancer is somehow associated with breast tissue. Cancer is more common in rapidly dividing tissue because every time when cells are born and die, in the cell cycle there is a possibility of error, DNA. Although this error can always be something insignificant, it can also be a cancer cell. Breast tissue, as the researchers found, is divided quite rapidly, so that the probability of error in such a division increases.
In any case, research on the topic continues. And while doctors urge women around the world regularly go to the doctor and not be afraid to do a breast ultrasound and a mammogram when recommended by a specialist. Because — truths — the sooner the disease is detected, the higher the chances of the patient that all will end happily.
