You perform an experiment and place a male stickleback fish in an environment with other male and female sticklebacks. You notice the male will attack and fight other males to the death. You observe that the male sticklebacks have red bellies and the females do not. You investigate to see if the male recognizes the red bellies and decide to place a red object in the environment. You record that the male attacks the red object. Based on an analysis of the data from your investigation, which conclusion can be made?
