Pheomelanin less common type of orange melanin, causes red hair, etc. Melanin produced by glands in the body known as melanocytes. Melanosomes are specialized organs inside of cells think of it as a clump or a grain of melanin (melanin is a dusty substance, but it tends to clump together). Level of ultraviolet radiation measured at the (spring and fall) e(cid:395)ui(cid:374)o(cid:454)es.

Second map is of uv radiation in various parts of the world. Greys, greens, yellows low levels, pinks and reds highest levels of uv radiation. If everyone did the same things all the time, societies would stagnate and there would be no progress: societies need deviance in order to define the boundaries of acceptable behavior.
