The concept of race is no longer considered scientifically valid, as there is little genetic difference between the so-called races, and those differences are mostly superficial. Distinguishing humans on the basis of minor differences or not on the original basis of the theory, humans are either one race or several thousand. The most obvious example of difference between races is the fact that while black and pacific-islander people are, obviously, black, all people have the same type of skin-coloring pigment ([[melanin]]), each race's skin color being dependent on the melanin content of the skin. | The concept of race is no longer considered scientifically valid, as there is little genetic difference between the so-called races, and those differences are mostly superficial.
