sciencehabit writes "Computer simulations of tiny robots with rudimentary nervous systems show that, over hundreds of generations, these virtual machines evolve altruistic behaviors. They begin to share small disks — a stand-in for food — with each other so that their comrades' traits are passed on to the next generation. Experts say the study sheds light on why various animals — from bees to humans — help each other out, even when it hurts their own chances to reproduce."
"Card readers? We don't need no stinking card readers."
-- Peter da Silva (at the National Academy of Sciencies, 1965, in a
particularly vivid fantasy)
