This discussion is based on an article by Elizabeth Kolbert (author of The Sixth Extinction: An Unnatural History), published in The New Yorker, August 8, 2011 (CLICK HERE for link to article). It outlines the development of DNA genomes for humans, Neanderthals, and others and illuminates the fact that many humans have a small percentage of Neanderthal genetic variants — indicating that interbreeding did occur. So, what does it mean to be “human?” How do we differ from the rest of the animals on Earth?
