Industry:Anthropology
A group of individuals arranged in rank order. In some non-human primate species, each community has a distinct male and female dominance hierarchy. Every individual is ranked relative to all other community members of the same gender. In the case of rhesus macaque females, rank is determined by the relative rank of their mothers. Depending on the species, male ranking may be similarly determined by the mother's rank or it may be earned in competition with other males. Individuals who are higher in the dominance hierarchy usually have greater access to food, sex, and other desirable things. See alpha male and female.
Industry:Anthropology
A similar evolutionary development in different species lines after divergence from a common ancestor that had the initial anatomical feature that led to it. Parallelism is thought to be due primarily to the independent species lines experiencing the same kinds of natural selection pressures. Parallelism is also referred to as parallel evolution. Parallelism results in homoplasies. See convergence.

A rare chromosomal abnormality in which there is a trisomy of chromosome 18. This inherited condition is also called Edward's syndrome. It is characterized by severe mental retardation, a small head with malformed ears set low, and a face with a pinched appearance. Other likely defects include a cleft palate, webbed hands, missing thumbs, clubfeet, as well as heart and genitourinary defects. Individuals with trisomy 18 usually die within a few months after birth.
