Interesting Findings And World Unfolding Through My Eyes.

Do You Know ?

There are 1.75 million animal species that have been noted and named by our scientific classification system. Of them, there are 5,800 types of mammal. All mammals are warm-blooded and have a four-chambered heart, but so do birds. Most mammals give birth to live young, but there are exceptions to that. Mammals all have hair, but again they share that trait with other creatures–in this case spiders. In fact there is only one truly defining characteristic of mammals that is unique, and that is the trait for with they are named: the mammary gland. All mammalian species posses a gland that secretes or oozes milk for the repast of their young. In most cases the mammary gland becomes enlarged during lactation, and diminishes to almost unnoticeable when the milk is unneeded. However, amidst all 5,800 mammals, there is only one species that has perpetually swollen mammary glands. Odds are you are a member of this strangely anomalous, difficult to explain species.

At first glance the human breast defies explanation, but there are those who have spent careers and lifetimes in pursuit of explaining the relative enormity of the bust. Theories about the abundance abound. As of yet there is no consensus as to why the human female is so endowed, but staying abreast of the emerging ideas can make for titillating research.

Every variety of mammal has some sort of breast. The feature that sets the human breast apart is that in relation to the size of the body, there is no other species that retains a breast in such a swollen state. Cattle teats can be proportionately larger, but only so long as the cow is lactating; the same is true of many other species. It seems logical, seeing how lactation can be a drain of resources, that the animal’s breasts would atrophy when not in use. Some early thought on the origin of the human breast stated that because of the breast's importance in nurturing the young, biology opted to supply extra fatty deposits to the mammary glands to help the race survive lean times of drought or meager foodstuffs. A fine idea, but it does little to explain the complex psychology surrounding the breast, and one should suppose the same phenomenon would be displayed in other species.

Blue Footed BoobieTherefore to handle the riddle of perpetual breasts a zoologist by the name of Desmond Morris attempted to apply gleanings from his animal research. Morris is probably best known for his 1957 art exhibition of paintings created by monkeys and his documentary series "The Human Animal". Morris has become a somewhat controversial figure by writing papers expounding on how certain human aspects may have evolved. Among the tenets that he's suggested is a need to exercise our inherent omnivorous heritage by eating everything, and speculation on the development of human breasts.Morris' hypothesis is that the breast is a purely erotic affectation–a piquing notion. Most creatures in the animal kingdom tend to have the most success mating in a "male aft" sexual position because of the placement of the genitalia.
