    1. HARs are short stretches of DNA that while conserved in other species, underwent rapid evolution in humans following our split with chimpanzees, presumably since they provided some benefit specific to our species. Rather than encoding for proteins themselves, HARs often help regulate neighboring genes. Since both schizophrenia and HARs appear to be for the most part human-specific, the researchers wondered if there might be a connection between the two.dfp.loadAds("right2","MPU2","dfp-right2-article-1")Advertisement

      Schizophrenia is unique to humans. There are also regions that human and other species have, but have undergone more rapid evolution in humans called Human Accelerated regions (HAR).

      Maybe these HARs and Schizophrenia are linked.

      Also HARs are regions whose purpose is to regulate the expression of other genes, not so much directly code for a protein.
