FRAGMENT FROM NATURE considers the phenomenon of host suicide, the sacrifice of individuals for the betterment of the population. This is not rare in biology and has been quite well studied. The function of host suicide is to thwart the reproductive strategy of the parasite. And curiously, some viral parasites have evolved cunning strategies of preventing host cell death.

STEP 3: SOPHISTICATED. "Some developed counterstrategies, learning to push opponents away from the object. One learned to grab the cube, then pin a smaller rival, preventing it from taking the cube back. As with organic life, the creatures evolved many body types and behaviors to achieve the same goal." https://lnkd.in/dD4T763 View in LinkedIn

STEP 2: GETTING BETTER. "Over time – Sims has run some experiments out to 300 generations – the creatures started behaving like real animals, wanting nothing more than to seize and keep the cube. Some developed arms to reach out and encircle it; others evolved large flat bodies to cover it. Some walked toward the cube, others hopped, paddled, or crawled." https://lnkd.in/dD4T763 View in LinkedIn

STEP 1: LUMPY START. "Two at a time were plopped down in an arena, facing a small cube. A battle commenced, and the computer measured the creatures' success in gaining control of the cube. Typically, the first generation did a lousy job. Most of the creatures simply sat there like, well, blocks; a few flopped or twitched, often away from the cube. But after each competition, the animal that had the better score was allowed to live – and to breed and mutate." https://lnkd.in/dD4T763 View in LinkedIn

HUMAN-FREE. "In an earlier art-science project, Evolving Virtual Creatures, Sims left higher intelligence out of the loop, letting the computer provide both the variation and the selection of "winners." The 3-D world of Evolving Virtual Creatures – with physical laws such as gravity, friction, and fluid viscosity – was populated by crude animals built from rectangular blocks." https://lnkd.in/dD4T763 View in LinkedIn

"THE EVOLVED VIRTUAL CREATURES project was developed in 1994 at Thinking Machines Corporation. I was an Artist in Residence there, and was given the task of showing the computational ability of their Connection Machine (one of the first parallel processing supercomputers) in a visually demonstrable way." https://lnkd.in/dqVFHaZ View in LinkedIn

E COLI ALTRUISM. "Here, we demonstrate evidence of such a low-cost altruistic act in Escherichia coli bacteria, which express an abortive infection system (Abi) that responds to lethal phage attacks by causing infected cells to die together with the infecting phage. From an evolutionary perspective, the expression of an Abi system could reflect an altruistic act that allows infected bacteria to commit suicide in order to prevent parasite transmission to nearby relatives." https://lnkd.in/d53-z28 View in LinkedIn
