What do the discoveries made by the scientists show?Summary:The book The History and Geography of Human Genes is based on the combined research of more than 50 years into the genetic

35、s of humans. It appears from this books finding that, if we disregard the different external physical features between different races, then we are all very similar under the surface.

47、s firm conclusion: once the genes for surface feature such as skin color and height are discounted, the “race are remarkably alike under the skin.
