　　Dimorphism is the condition where the two sexes of the same species exhibit different appearances. The professor uses the example of the bird of paradise to illustrate what is dimorphism.

　　The male and female birds of paradise appear differently in their colors and sizes. The male birds have bright and beautiful feathers to attract female birds so that they can produce offspring. The female birds on the other hand, are less colorful. Their main responsibility is to take care of the young, not attracting the opposite sex. Additionally, the dull color is safer for the female birds to avoid being found by the predators.
