Depression linked to genes inherited from Neanderthals: study

After a massive study linking tens of thousands of modern people's medical records to their genetic histories, certain genes inherited from Neanderthals have been linked to psychiatric disorders, blood clotting and addictive behaviors, researchers said Friday. This study, in the February 12 edition of the journal Science, is the first to compare Neanderthal DNA in the genomes of a large population of adults of European ancestry -- some 28,000 people -- and their health records to show a "subtle
