3. Informative article. Thanks for posting.

Here is just one of several interesting passages from the article:

Modern humans are the only humans alive today, but Earth was once home to a variety of other human lineages. The Neanderthals were once the closest relatives of modern humans, with the common ancestors of modern humans and Neanderthals diverging between 550,000 and 765,000 years ago. Neanderthals and modern humans later interbred — nowadays, about 1.5 to 2.1 percent of DNA of people outside Africa is Neanderthal in origin.
