Neanderthal DNA contributes to Human Genome

      Although the Neanderthals haven't been around for over 40,000 years a part of them still lives on today and it can be found in modern humans. Small bits and pieces of their genome is said to be observed.Recent research as been able to to show evidence of Neanderthal DNA sequence in today's humans and that it influences how our genes are expressed. The influence helps regulate what genes turn off and which ones turn on effecting such traits as height, schizophrenia, and even lupus among others.
      Previous studies have been done to find correlation between Neanderthal genes and traits and those of modern humans but they were not as successful. There was some evidence however that their traits could have effected depression and fat metabolism but not as supported as the recent studies. The Neanderthal gene ADAMTSL3 was uncovered in modern humans that helps to decrease the risk of schizophrenia while also influencing height, Researchers are pleased with these discoveries but say further investigation and studies need to be done.
