"So there was only one species to begin with" The idea that all life shares a common ancestor does not mean that there was only one species to begin with. There could have been many species who contributed genetic material to a common ancestor, and then eventually died out. The article is poorly written because it doesn't make it clear whether the gene swapping occurred before or after the common ancestor. |

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?
