Players start with a hand resembling primordial ooze, but attempt through successive generations to "evolve" it into something more useful. But unlike Lamarck's giraffes, they may find themselves competing with others for the very same improvements. In the end, the player who has accumulated the best Poker hand wins.
Can be played using a standard Poker deck without Jokers. Published in the April 1999 issue GAMES (the magazine) and as part of Chief Herman's Next Big Thing as Darwinian Poker.
