Around the 20,000 generation a new "strain" of bacteria started showing very different signs than its predecessors...it had gained the ability, previously unseen, to use a compound called citrate. To create comparisons, the researchers froze ancestral strains in order to be able to observe them (E. Coli still remains viable in these temperatures). Can't wait to get some of this peer reviewed and see similar experiments done over the course of my life time!

More strikingly, however, he found that one of the 12 bacterial lines he has maintained has developed into what he believes is a new species, able to use a compound in the solution called citrate — a derivative of citric acid, like that found in some fruit — for food.

There are white people and black people and asians... doesn't mean we are all different species, just variations of humans. So far it looks like a variation of E Coli. I don't know much about this though.
