I went back and re-read the article.

I took it at first to mean common ancestor in terms of a single ancestor for a particular species. But then you guys seem to think it means a common ancestor for all life.

I found it confusing. Meta: I have no idea why my comment was voted down so much. I did not understand it, and I still do not. Seems like an admission of that along with an explanation from other commenters would be a good thing, right? Saying I don't know and having people help me -- reason for the board, or not?

I have no idea what's up with comment moderation, but it's clearly been going downhill. It's probably best to just ignore it.
