Sentences with phrase «modern human traits»
More recently, scientists have identified parts of the human genome carrying Neandertal genetic variants, but — in part because Neandertal - derived DNA is so hard to identify and also because of the expense of performing tests for its influence on individuals — scientists still don't fully understand how Neandertal - derived variants influence modern human traits.
