overhaul of the genetic blueprint -- perhaps much more so than the evolution of other biological traits," he said. But how did human ancestors encounter an environment where selection for better brains suddenly became such a prominent force? Lahn sug...
Federal/private partners launch resource for diabetic kidney disease gene studies
