There is no clear biological basis for race as we define it now, but there are shared traits based on geographical origin.

A distinction without a difference. The basis of the article is that geneticists can look at your DNA and easily classify you into one of the five main races, and with more markers can further classify you into your ethnicity. So YES, there is a clear biologic basis for race: your DNA. It doesn't get any clearer than that, does it?
