Laboratory born Calotes versicolor hatchhngs were reared for 15 days in pure or mixed sibships or singly in isolation and then tested for their kin discrimination abihty. As C. versicolor orients itself visually, visual displays like push-ups, guiar extensions, and distance between the test individuals were used as indicators of arousal/aggression towards the opponents (famihar vs. famihar/unfamiliar sib or non-sib). The hatchhngs exhibited aggressiveness towards unfamihar sibs as well as non-sibs in the form of push-ups and guiar extensions; they also remained at a longer distance from each other. In contrast, they did not exhibit such behaviors against famihar individuals regardless of their relatedness, and stayed closer to each other. In tests involving once famihar individuals, sib, or non-sib reared together for 15 d from hatching and then separated for 7 or 30 d, the lizards showed aggressiveness towards each other following 30 d separation. A greater number of push-ups and guiar extensions were exhibited by the test individuals after 30 d separation compared to those separated for 7 d. Thus, in this non-social lizard, there is no kin discrimination. An early dispersal of hatchhngs in this species may have led to a loss of kin discrimination. However, familiar individuals are recognized as long as they continue to remain famihar thereby suggesting a 'dear enemy phenomenon'.
