HeLa cells - human cervical cells containing 82 chromosomes that have been cultured in the lab.
Canine transmissible venereal tumor cells - originally canine cells that are now a contagious virus.
Devil facial tumor disease - contagious cancer that spreads among Tasmanian devils via facial bites.
All of these are immortal cell lines that were originally cells of the species they infect (with the exception of HeLa which now only exist in labs) and live on in a virulent form.
So the whole "have you ever seen a dog change into a cat?" question - No, but we've seen a dog, a human and a Tasmanian devil "turn into" a virus. Does that count?

arewethereyet - While it may be true that they ARE cells that have "gone bad", they CAN survive outside of their original host - contagious means they can transfer to another organism, in this case it has only been members of their own species but that has only been due to the way in which they are transfered.
And yes, most real viruses are not cellular, these cancerous cells certainely act like viruses, despite their classification.

Please, if you're just going to argue that viruses and bacteria only evolve into different strains you're an idiot - the matter at hand here is that animal cells - including human cells - can evolve into virulent cancer cells. That is one form of life essentially evolving into another, not simply a different strain of the original.
