A progressive, irreversible disease characterized by degeneration of brain cells that commonly result in severe loss of memory, the ability to think, and pay attention. There are also usually major changes in personality. Alzheimer syndrome most often occurs in late middle and old age. Genetic factors probably play a role since this syndrome is more common in some families.

A genetically inherited sex chromosome abnormality only affecting females. Women with Turner's only have one X chromosome--their genotype is X0. These individuals are short in stature, averaging 4'7" and have distinctive webbed necks (i. E. , extra folds of skin). They have exceptionally small breasts and generally lack secondary sexual characteristics. Their ovaries do not develop normally and they do not ovulate. They are in a sense postmenopausal from early childhood and are sterile. In some individuals, there is slight mental retardation. Turner syndrome is rare--current estimates of its frequency range from 1 in 3000 to 1 in 10,000 females.

A hypothesis to explain the origin of modern Homo sapiens. It proposes that modern people only evolved from archaic humans in Africa and that these new people expanded into Europe and Asia replacing all existing older populations. In other words, we all have relatively recent African ancestry. See regional continuity model and assimilation model.
Industry:Anthropology
A group of similar fossils considered to be members of the same species because the range of their morphological variation does not exceed the range of variation of a living species. See species.

A genetically inherited disease in children that results in chronic fluid development in the lungs, making breathing difficult. This disease also prevents normal absorption of fats and other nutrients from food. Cystic fibrosis occurs as a result of inheriting a recessive allele for if from both parents. This is ultimately a fatal disease, but with modern medical care, about 2/3 of the people with it survive into early adulthood. About 30,000 people have cystic fibrosis in the U. S. Today.
Industry:Anthropology
A date that places an event in its chronological position with reference to a universal time scale such as a calendar. Such dates usually are given in terms of the number of years before or after a calendar starting point. For instance, 1950 B. C. Was 1950 years before the beginning date of the Gregorian calendar, which is commonly used today. Chronometric dating methods include the use of written records, dendrochronology, and radiometric methods. See relative date.
