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 ...
A presumed human "race" consisting of Europeans and other closely related people. The classification is based on the discredited typological model. The term "Caucasoid" was derived from the Caucasus Mountains on the southeast fringe of Europe between the Black and Caspian Seas. This region was once thought to be the homeland of Indo-Europeans.

A pneumonia-like accumulation of fluid and swelling in the lungs. Like cerebral edema, it can be caused by hypoxia at high altitude. While pulmonary edema is potentially life threatening, it generally is less likely than cerebral edema to result in death if treated in time.
Industry:Anthropology
A more or less distinct group of individuals within a species who are reproductively isolated from other groups. In other words, they restrict their mate selection to members of their own population. This is usually due to geographic and/or social barriers to mating with outsiders. Members of a completely isolated small population tend to have similar genetic characteristics due to generations of inbreeding.
Industry:Anthropology
A relative dating method based on the association of early human sites with changing features of the land, such as the advance and retreat of glaciers or the rise and fall of sea levels. When these events are well dated, geochronology could be considered a reliable calibrated relative dating technique. Associated evidence may be changes in the frequency of plant species measured by pollen count and other kinds of paleoecology evidence.
Industry:Anthropology
A biological trait that has changed over time from the ancestral form and/or function that was present in the species from which it came.
Industry:Anthropology
A radiometric dating method based on the changing ratio of argon-40 to argon-39 with the passage of time in volcanic rock or ash. This technique was derived from potassium-argon dating. The argon-40/argon-39 method is usually more accurate than potassium-argon dating and doesn't require as large a sample.
Industry:Anthropology
A diagnostic procedure for pregnant women to determine whether or not their fetuses have gross chromosomal anomalies. It involves sampling the liquid immediately surrounding a fetus within the amnion. This amniotic fluid is extracted through the mother's abdominal and uterine walls with a hypodermic needle. The amniotic fluid mostly contains fetal urine but also has millions of fetal skin cells that can be cultured to produce a karyotype. There is 99+% accuracy in diagnosing Down syndrome and most other gross chromosomal aberrations including neural tube defects such as spina bifida.
Industry:Anthropology
A date that gives the time of an event only with reference to another event that is not worldwide in scale. It only indicates that one event occurred earlier or later than another. For instance, the observation that strata 2 is younger than strata 1 beneath it in a geological deposit does not provide information about how many years ago strata 2 was laid down. It only indicates its age relative to strata 1. In addition to the use of stratigraphy, relative dating methods include biostratigraphy and fluorine analysis dating. See chronometric date.
Industry:Anthropology
A gland surrounding the urethra at the base of the bladder. It secretes most of the seminal fluid that is expelled with sperm cells during ejaculation.
Industry:Anthropology
A bony arch extending horizontally on either side of the face just below the eyes on primates and many other vertebrates. The major jaw muscles pass under these two arches on their way up to the temporal areas of the skull for attachment.
