Shreeve

      Shreeve has a positive opinion about use of the word "race" by scientists. He thinks race is biological problem, and is human's variation created by interaction between geography and inheritance. An anthropologist Jonathan Marks says, as Shreeve draws, race should be considered as biological category, not cultural one. On the other hand, unlike anthropologists, medical researchers seem to trust the reality of racial classification.  However, Shreeve disagree with medical researchers' idea because of lack of enough data. In the end, Shreeve cites Smouse's words. He says, of course there are generic diversity between groups of human, but such differences does not matter when we compere them with those between chimps and humans.

　　　I thought this text is not so organized but I could understand mostly. His main idea is,I think, race is a perspective thing. And I think so too. There is no well-established classification of race. We cannot and should not rank races based on genetic differences.
