seems like this is a pc article to game "eve" as first.

If anything it tells me that the survival characteristics of the Y carrying humans had more selection activity than the X. Thus given hunting and warfare etc., the weaker Y's were killed off by environment and stronger Y's. The X's were not under such survival strain and thus did not have to be as genetically selective for survivale traits.

The X is "older" because it has had to change less. (keep in mind all men are X and Y not just Y. women=XX men=XY Just in case anyone missed that part from the article) The Y is newer because the Y model one was killed off in favor of Y model two.

(s)so in essence this ABC story is saying that women are less evolved than men. (/s)

Everybody alive today has inherited their mitochondrial DNA from the same woman who lived 120 million years ago. And everybody alive today has inherited their cellular DNA from the same man who lived 60 million years ago. That's what the article is saying.
