There is an argument that as they are independent and an immortal cell line, that they could be considered an example of a speciation event, but all that means is that we've chosen to call them something for convenience and to distinguish them from other clumps of human cells. They are indeed human cells. Very interesting ones, but indisputably human I would think that by the standard definition of a species a cell line cannot qualify. A species is a group of individuals who can or do interbreed. I don't know how a cell culture can qualify a species. _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
