Mitochondrial Eve is the mother of an unbroken line of mothers of humanity that dates back somewhere around 200,000 years ago. The idea that we can ALL be tide back to one person was cool to me. And i just picture her on an open field with children around her staring out in protection of the kids that will give rise to skyscrapers, wars, music, and everything that we are as a species. She'd be protecting her offspring and in doing so, safe guarding all of the human race. Probably needs some more study cause its kind of complicated and I'm not sure I understand the WHOLE concept, but I thought it was a neat jumping point.
