Eyebrow

The eyebrow is an area of thick, delicate hairs above the eye that follows the shape of the lower margin of the brow ridges of some mammals. Their main function is hypothesized to prevent sweat, water, and other debris from falling down into the eye socket, but they are also important to human communication and facial expression. It is not uncommon for people to modify their eyebrows by means of hair addition, removal and makeup.

Functions

Physical

It is believed by anthropologists that the main function of the eyebrow is to prevent moisture, mostly salty sweat and rain, from flowing into the eye. Greek physician Herophilos, in his treatise "Anatomy," was among the first to hypothesize such a theory, proposing that the eyebrows are "adorned with hair, so that if copious perspiration came [down], it would be contained by this 'check-point' of hair placed in its way until it is wiped off, so that it could not obstruct the eyes." The typical curved shape of the eyebrow (with a slant on the side) and the direction in which eyebrow hairs are pointed, make sure that moisture has a tendency to flow sideways around the eyes, along the side of the head and along the nose. The slightly protruding brow ridges of modern humans could also be used as a defense structure against the floods of moisture. Desmond Morris, discussing the possible function of the eyebrow in human evolution, criticized this suggestion as non-effective and suggested that the primary function of the eyebrows is to signal the changing moods of their owners. Together with the brow ridges, the eyebrows also shade the eyes from sunlight. Eyebrows also prevent debris such as dandruff and other small objects from falling into the eyes, as well as providing a more sensitive sense for detecting objects being near the eye, like small insects.

By 2013, its population had grown to 34,658. Sometimes referred to as "90210", one of its primary ZIP codes, it is home to many actors and celebrities. The city includes the Rodeo Drive shopping district and the Beverly Hills Oil Field.

History

Early history

Gaspar de Portolá arrived in the area that would become Beverly Hills on August 3, 1769, travelling along native trails which followed the present-day route of Wilshire Boulevard.

The area was settled by Maria Rita Quinteros de Valdez and her husband in 1828. They called their 4,500 acres (18 km²) of property the Rancho Rodeo de las Aguas. in 1854, she sold the ranch to Benjamin Davis Wilson (1811–1878) and Henry Hancock (1822–1883). By the 1880s, the ranch had been subdivided into parcels of 75 acres (0.30 km²) and was being rapidly bought up by anglos from Los Angeles and the East coast.
