There is an overbearing censorship to the way we are allowed to think and talk about the diversity of people on Earth. Officially we are all the same: there are no races. Flawed as the old ideas about race are, modern genomic studies reveal a surprising, compelling and different picture of human genetic diversity. What this all means is that, like it or not, there may be many genetic differences among human populations—including differences that may even correspond to old categories of ‘race’—that are real differences in the sense of making one group better than another at responding to some particular environmental problem. This in no way says one group is in general ‘superior’ to another, or that one group should be preferred over another. But it warns us that we must be prepared to discuss genetic differences among human populations.
The good news: Helena Cronin and Simon Baron-Cohen are as smart as I am.
Freeman Dyson and Craig Venter? Not so much.
