I came across this link, which outlines different aspects of the issue.
Extract from article:
"The debate about race is not a debate about whether differences exist between human populations. Jon Entine, a staunch defender of the idea of race, defines race as ‘human biodiversity’. That is meaningless. No one, on either side of the debate, would deny that there are a myriad of differences between different human populations.
The real debate about race is not whether there are any differences between populations, but about the significance of such differences. The fact that a BMW saloon is of a different colour to a Boeing 747 is of little significance to most people. The fact that one has an internal combustion engine and the other a jet engine is of immense consequence if you want to travel from London to New York. But if you are a Yanomamo Indian living in the Amazon forest, even this difference may not be of that great an import, since it is quite possible that you will be unable – or will not need – to use either form of transport. If we want to understand the significance of any set of differences, in other words, we have to ask ourselves two questions: Significant for what? And in what context? One of the problems of the contemporary debate about race is that these two questions get too rarely asked."https://kenanmalik.wordpress.com/2012/03/04/why-both-sides-are-wrong-in-the-race-debate/
