- I think you miss the point of the Eve studies. Certainly they will point to
- a female as the 'source' of all people, because they can only look at females
- anyway. They are looking for the number of 'family trees' in mankind - are
- we ALL descended from one family, or did H. sapiens develop independently
- in several areas of the world? The Eve studies are an attempt to find if
- all humans have a single common (hominid) ancestor.
