Dude! Slime molds are cool

Fun thing from bio today:
Slime molds: single cells mass together to form slug. Reproduction happens best when some cells hold up the others. "Sucker" cells become the foot; "selfish" cells crawl up and reproduce. How does cooperation ever continue? Kin preference - the nice, cooperative cells group together and the mean, selfish cells do the same as generations pass. So cooperative cells work together to shove away the selfish jerks. Fascinating.

If you could make two different groups of selfish cells, maybe you could reproduce the Democratic & Republican parties?
