reaction to Diamond

Race Without Color by Jared Diamond deals with classification of humans beings by color. He points out Human beings tends to judge others by appearance and this is a common sense of view of race not based on science. Although he introduces us other ways of classification of humans by like genes resistant to malaria or the shapes of fingerprints, those classifications are also vague. In the conclusion, in today's world when there is much diversity in appearance, it is unnecessary to continue to make snap judgement.

At first I am surprised at how changeable classification of humans is. For example, If we judge race by the ability to digest lactase, some Europeans and black Africans are categorized into the same group of race ,though they are totally different in appearance. At the same time, this fact make me realize how difficult it is to categorize humans even if we use science. I learned that just because judging people by appearance is said to be an unfavorable thing does not necessarily mean we should judge race by science.
