What Science Says About Race and Genetics | Nicholas Wade

An excerpt from Nicholas Wade’s book, A Troublesome Inheritance, on the possible links between evolution, societies and genetics.

Racism and discrimination are wrong as a matter of principle, not of science. That said, it is hard to see anything in the new understanding of race that gives ammunition to racists. The reverse is the case. Exploration of the genome has shown that all humans, whatever their race, share the same set of genes. Each gene exists in a variety of alternative forms known as alleles, so one might suppose that races have distinguishing alleles, but even this is not the case. A few alleles have highly skewed distributions but these do not suffice to explain the difference between races. The difference between races seems to rest on the subtle matter of relative allele frequencies. The overwhelming verdict of the genome is to declare the basic unity of humankind.

Civilizations may rise and fall but evolution never ceases, which is why genetics may play some role alongside the mighty force of culture in shaping the nature of human societies. History and evolution are not separate processes, with human evolution grinding to a halt some decent interval before history begins. The more that we are able to peer into the human genome, the more it seems that the two processes are delicately intertwined.

A more reasoned and nuance approach that the “triple package” approach. Margaret Wente has a less nuanced summary of Wade’s arguments (What if race is more than a social construct?) but better to read this complete excerpt.
