The article covers new research by Carl Woese at the U of Illinois, suggesting that life began multiple times but was only successful three times. Quote from Woese: "The question is whether the universal common ancestor was an individual or whether it was a community of organisms that were exchanging genes. The evidence indicates that there was a community of organisms exchanging genes and that three dominant cell lines emerged."
