Massive Project Will Reveal How Humans Continue to Evolve by Gregory Mone
By comparing differences among those groups’ DNA, HapMap gives scientists a better shot at distinguishing the genetic factors involved in disease from the environmental ones. Ultimately, it will help them explain why, for instance, some people have a higher or lower risk of certain illnesses. And once scientists understand how deleterious genes affect various populations, they’ll be better equipped to develop more-effective, targeted drugs to combat them.
