Sometimes it is claimed by those who argue that race is just a social construct that the human genome project shows that because people share roughly 99% of their genes in common, that there are no races. This is silly.

Of course, individuals vary greatly within each racial group and should be treated as such.

Those objecting to the concept of race argue that the taxonomic definitions are arbitrary and subjective.

Race differences show up early in life.

I was born in Bournemouth, England, in 1943.

I then moved to the University of Western Ontario where I was made a full professor in 1985.

Deconstructing the concept of race not only conflicts with people's tendency to classify and build family histories according to common descent but also ignores the work of biologists studying non-human species.
