Dig into why ethnic diversity is so important to medical research when creating new treatments and medicines for diseases.

--

While all humans share 99.9% of our DNA, differences in the remaining 0.1% hold important clues about the causes of diseases—and their potential treatments. The problem is, the genetics that researchers are combing through are heavily biased to those of people from European descent, and often overlook other ethnicities. Greg Foot explains the importance of ethnic diversity in medical research.
