Agree that there are very important genetic components to disease (it's what I study), but the article points out that the "races" we use now are pretty arbitrary and do a bad job categorizing people's generic makeup. For example, there is more genetic diversity in Africa than the rest of the world combined, yet we in the United States basically just would think of their race as "African," and this is not a very helpful description.
