Sexual dimorphism in human sacrum



Sexual dimorphism in human sacrum Abstract. Among dioecious flowering plants, females and males often differ in a range of morphological, physiological, and life-history traits. This is referred to as sexual dimorphism, and understanding why it occurs is a central question in evolutionary biology. Sexual differences in size and shape are common across the animal kingdom. The study of sexual dimorphism (SD) can provide insight into the sexual- and natural-selection pressures experienced by males and females in different species. Arachnids are diverse, comprising over 100,000 species, and exhibit some of the more extreme forms of SD in the animal kingdom, with the males and females of.. dimorphism [di-mor´fizm] the quality of existing in two distinct forms. adj., adj dimor´phic, dimor´phous. sexual dimorphism physical or behavioral differences associated with sex. having some properties of both sexes, as in the early embryo and in some hermaphrodites. sex·u·al di·mor·phism the somatic differences within species between male and..

In some cases, sexual dimorphism enables males and females to exploit different food resources, thus increasing their collective ability to find food Sexual dimorphism in human sacrum. Psychology Definition of SEXUAL DIMORPHISM: the existence in a species of males and females that are different from other males and females. See sex characteristics; sex differences. Sexual dimorphism is a concept in biology. It means that the male and the female of a species look noticeably different. The word comes from the Greek: di (two) and morphe (form). It is the most common type of polymorphism. It may be the result of sexual selection, that is, competition between members of the same species for reproduction. The relationship between feeding ecology and sexual dimorphism is examined in a speciose South African monkey beetle clade. We test whether feeding and mating at a fixed site (embedding guild) is associated with greater levels of sexual dimorphism and possibly sexual selection than species using unpredictable feeding resources (non-embedding guild). Sexual dimorphism is the difference in morphology between male and female members of the same species. Sexual dimorphism includes differences in size, coloration, or body structure between the sexes. For example, the male northern cardinal has a bright red plumage while the female has a duller plumage. Male lions have a mane, female lions do not. Sexual dimorphism is the term that refers to differences between males and females of the same species, and is most obvious as differences in external appearances. However, there can also be sexual dimorphism of internal organs and biological functions, including the immune system. Dimorphism definition, the occurrence of two forms distinct in structure, coloration, etc., among animals of the same species. See more.
