Sexual dimorphism refers to the physical differences between males and females of a species. These differences can include size, coloration, and other characteristics. In mammals, including humans, sexual dimorphism can vary widely. For example, male lions are larger and have a mane, while female lions do not.
Male and female primates also exhibit sexual dimorphism, with males often being slightly larger than females. It is important to note that sexual dimorphism can vary greatly between different mammal species.
