Genetics is the new tool for researchers to understand the evolution of mental disorders in humans
Evolution usually eliminates debilitating features, yet this is not the case for human psychiatric disorders. The understand why, researchers are now using human genome databases.

One study showed that over the last 2000 years evolution selected DNA variants that protect against schizophrenia. Another study discovered a link between environment and mental illness: people living in regions with colder winters were more genetically prone to schizophrenia. Several of the teams involved in these studies presented their findings at the American Society of Human Genetics (ASHG) meeting in Orlando, Florida, in late October.

Studying the role of genetics in the evolution of psychiatric disorders is not easy, but the genomic data is a leap forward towards understanding mental problems.
