SEXUAL DIMORPHISM Meaning and
Definition
-
Sexual dimorphism refers to the phenotypic differences between males and females of the same species, specifically in terms of their physical characteristics or traits, that are directly related to their reproductive roles. This phenomenon is commonly observed in many organisms, particularly higher animals, where males and females exhibit distinct morphological, physiological, and/or behavioral variations.
These variations are primarily driven by the different biological imperatives associated with reproduction. In sexually reproducing species, males typically contribute sperm while females provide eggs, leading to distinct physiological adaptations. Sexual dimorphism can manifest in various ways, such as differences in body size, coloration, ornamentation, skeletal structures, and in some cases, behavioral patterns.
Sexual dimorphism may be influenced by natural selection, sexual selection, and other evolutionary forces. In some species, it can be extreme, with males and females adopting dramatically divergent forms or behaviors. For instance, in certain bird species, males may evolve bright, flashy plumage or develop elaborate courtship displays to attract mates, while females exhibit more camouflaged, subdued coloration to enhance their survival and the care of offspring.
Understanding sexual dimorphism is important for studying and comprehending evolutionary biology, reproductive strategies, and ecological dynamics. It provides insights into the social structure, mating systems, and reproductive success of species, as well as the mechanisms underlying sexual selection and mate choice. By observing and analyzing sexual dimorphism in various organisms, researchers gain valuable knowledge about the diverse strategies employed by males and females to ensure successful reproduction in the natural world.

Etymology of SEXUAL DIMORPHISM
The word "sexual dimorphism" is derived from several Greek and Latin roots.
The term "sexual" comes from the Latin word "sexus", which means "gender" or "sex".
The term "dimorphism" is a combination of the Greek words "di-" meaning "two" and "morphe" meaning "form" or "shape".
Put together, "sexual dimorphism" refers to the phenomenon in which two different forms or shapes of a species exist between males and females in terms of physical characteristics and traits related to reproduction and sexuality.
