Evolution In Evolution, players adapt their species in a dynamic ecosystem where food is scarce and predators lurk. Traits like Hard Shell and Horns will protect your species from Carnivores, while a Long Neck will help them get food that others cannot reach. With over 4,000 ways to evolve your species, every game becomes a different adventure.Evolution packs a surprising amount of variety for a game with simple rules. The variety comes from the synergies between the trait cards and from the different personalities at the table.
