Dominant Species is a game that abstractly recreates a tiny portion of ancient history: the ponderous encroachment of an ice age and what that entails for the living creatures trying ot adapt to the slowly-changing earth. Each player will assume the role of six major animal classes - mamma, reptile, bird, amphibian, arachnid or insect. Each begins the game more or less in a state of natural balance in relation to one another. But that won't last: It is indeed "survival of the fittest."
