Christina Warinner : Dental information is valuable information . Our team is taking this research a step further to ask whether we can also recover DNA and proteins that can tell us more about the health status and diets of ancient humans . Studying genome is n't enough ; we need to study evolution of human diseases , she says . Warinner : By extracting DNA from fossilized tartar , we learn about diseases of ancient humans . She says understanding our evolutionary vulnerabilities will help us improve our health .
