My understanding of using mitochondrial dna was that there were fewer, and they're easier to map. That came from 23. I'm not familiar with a mutation rate premise. Because of my source I'm familiar with the geographical visual of movement.

Example :

This would not be a steady rate because the different areas merging wouldn't be a steady rate. Migration doesn't work that way. The theory you're familiar with seems the opposite of the one I'm familiar with. Do you have any information I can read about it?

Edit : The Seven Daughters of Eve. I have read the book, because it's heavily cited.
