Creatures (artificial life series)

Creatures is a series of artificial life (alife) computer programs. It was created in the mid-1990s by English computer scientist Steve Grand. It was developed by Millennium Interactive. The game is about raising alien creatures known as Norns. This involves teaching them to , helping them explore their world, ing them against other animals, and breeding them. The player can also teach the creatures to speak a language, and can then tell their creature to do something by typing in instructions.
Between 1996 and 2001, six "Creatures" games were released. 
The program was notable for being one of the first commercial products to create artificial-life animals using genetics, biochemistry and neural network brains. This meant that the Norns and their DNA could "evolve" in many different ways. By breeding certain Norns with others, some traits could be passed on to younger generations. The genetics in "Creatures" are slightly different from human genetics; they are haploid.
