Sexual dimorphism
Sexual dimorphism refers to the differences in size, shape, color, or behavior between males and females of the same species. These differences can be quite pronounced in some animals, such as peacocks, where males have extravagant plumage to attract females, while females are more understated. In other species, such as many mammals, males may be larger or have different physical features. Sexual dimorphism is often a result of evolutionary pressures, such as mate selection, where traits that enhance reproductive success become more pronounced over generations.

Sexual dimorphism refers to the differences in physical traits between males and females of the same species. These differences can be seen in size, color, shape, and even behavior. For example, in many bird species, males are often more colorful to attract females, while in some mammals, males may be larger to compete for mates. Sexual dimorphism arises from evolutionary pressures and plays a role in reproduction and survival. Understanding these differences helps us appreciate the diversity of life and the various strategies species use to thrive in their environments.
