Dipsosaurus dorsalis
The behavior patterns of closely related groups of animals often show both similarities, consistent throughout the group, and differences. The differences may exist in some ritualistic pattern, such as display. It is probable that such differences are the result of environmental selection evolved along with morphological and physiological speciation. A study of behavior differences may reveal the direction of such changes and offer information to aid in establishing relationships between genera and species within the group. The lizards of the family Iguanidae perform display movements and posturing which are ritualistic in character. Their rituals are a part of the social behavior patterns of aggression, spacing, reproduction and social status. The following study is a part of a program investigating the comparative behavior of the iguanid lizards, with special emphasis on ritualistic patterns.
