This really cool animation shows everything we know as a result of that Y chromosome, combined with archaeology, fossil records and climatology. Be sure to click on the little cloud symbol where it appears, and you'll get additional notes about climate change during that period. Don't miss the dramatic turn of events 74000 years ago!

Mother of all humans lived 200,000 years ago

The most robust statistical examination to date of our species' genetic links to "mitochondrial Eve" -- the maternal ancestor of all living humans -- confirms that she lived about 200,000 years ago. The Rice University study was based on a side-by-side comparison of 10 human genetic models that each aim to determine when Eve lived using a very different set of assumptions about the way humans migrated, expanded and spread across Earth.
