Company Profile:
Founded in 1946, Palomar College is a public two-year community college in the city of San Marcos, located in north San Diego County, California. Palomar offers over 300 associate degree, certificate programs and is designated by the U.S. Department of Education as an Hispanic-Serving Institution ...
Within the same species of warm-blooded animals, individuals from populations living in colder environments usually have greater body mass than do those from populations in warmer areas. This is because of the selective advantage it provides. A massive body produces more internal heat and radiates relatively less of it into the surrounding environment because the skin surface area is relatively smaller. Subsequently, a massive body produces and retains more heat. Bergmann's Rule was named after Carl Bergmann, a19th century naturalist. See Allen's Rule.

Within the same species of warm-blooded animals, individuals from populations living in colder environments usually have shorter appendages than do those from populations in warmer areas. This is because of the selective advantage it provides. Short arms, legs, and other appendages have relatively less skin surface area that can radiate heat into the surrounding environment. Subsequently, the body retains more of it. Allen's Rule is a corollary of Bergmann's Rule. Allen's Rule was named after Joel Allen, a 19th century naturalist.

Within the same species of warm-blooded animals, there is a tendency for darker, more heavily pigmented skin to occur in animals near the equator and lighter pigmented skin farther from it. This is because of the selective advantage the coloration provides. Heavy pigmentation protects from skin cancer caused by ultraviolet radiation from the sun. However, too much pigmentation can significantly reduce the skin's ability to produce vitamin D, which is necessary for the absorption of calcium and phosphorus from food. Open country close to the equator typically experiences high amounts of intense ultraviolet radiation while temperate and arctic regions have relatively little. Subsequently, heavy skin pigmentation is an advantage near the equator but a disadvantage farther away from it. Gloger's Rule was named after Wilhelm Gloger, a 19th century naturalist.
Industry:Anthropology
The study of annual growth-rings of trees, usually for the purpose of chronometric dating logs found in association with relatively recent archaeological sites. Tree-ring sequences also are used as records of cycles in local climates.

Industry:Anthropology
The study of biological inheritance patterns and changing gene pool frequencies in populations largely through the determination of allele frequencies. Population geneticists also identify processes resulting in evolution. See synthetic theory of evolution.
Industry:Anthropology
The study of conditions, processes, or results of diseases. Pathology also is used to refer to any abnormal physiological condition.
Industry:Anthropology
The study of earlier forms of life present in the fossil record. See paleoanthropology.
Industry:Anthropology
The study of gene structure and action and the patterns of inheritance of traits from parent to offspring. Genetic mechanisms are the underlying foundation for evolutionary change. Genetics is the branch of science that deals with the inheritance of biological characteristics.
Industry:Anthropology
The study of geological strata, or layers of rock or soil, usually for relative dating based on the principle of superposition.
