4 major races. The world population can be divided into 4 major races, namely white/Caucasian, Mongoloid/Asian, Negroid/Black, and Australoid.This is based on a racial classification made by Carleton S. Coon in 1962 (in common usage the âËCapoidââ¢ and âËCongoidââ¢ groups classified by Coon is merged under âËNegroidââ¢).he United Nations, in a 1950 statement, opted to âdrop the term âraceâ altogether and speak of âethnic groupsâ. In this case, there are more than 5,000 ethnic groups in the world, according to a 1998 study published in the Scientific American. This fact is verified on: February 20, 2010.
I read somewhere that there are over 16 million different colors. 16 million is an estimate of how many different colors a 24 bit RGB computer monitor can simulate. This has no relevance to how many different colors the human eye can distinguish. Just as there are infinitely many numbers between 380 and 740 - including all of the fractions, of course - so there are infinitely many wavelengths between 380 and 740 nanometers - the visible spectrum of light. That doesn't even count the different tints and shades obtained by mixing in white, black, etc.
