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.

So all humans living today can trace their ancestry to one man and one woman? Seems like I've heard that somewhere before.

Math aside, why then don't we see a piece of the progenitors of either?

I understood that. It seems the article is written with a bend to politics rather than science. There is more spin by omission than hard science.

Just because certain parts are older than other parts means nothing.

Remember its all a matter of who gets killed off vs who does not.

DNA is DNA, so the sequence which forms mitochondria is older than the DNA which forms the other parts of the cell are 60 million years old. All parts of the cell are made of DNA. The descriptions in this article are sloppy and not to be taken seriously.

Hence my (s). It can be spun any which way.
