Anthropology dating techniques

Dating techniques are procedures used by scientists to determine the age of a specimen. Relative dating methods tell only if one sample is older or younger than another sample; absolute dating methods provide a date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element is converted into another radioactive isotope or non-radioactive product at a regular rate. Others, such as amino acid racimization and cation-ratio dating, are based on chemical changes in the organic or inorganic composition of a sample.

Why Anthropology? | Anthropology | Mesa Community College

Artifact : an object formed by humans. Carbon : a chemical element important to life on Earth; it is one of the most abundant elements in the universe. Carbon isotopes : atoms of carbon that have different numbers of neutrons; isotopes are sometimes used to determine the diet of mammal herbivores by analyzing the carbon in fossilized teeth. DNA : deoxyribose nuleic acid, which carries genetic information; it is composed of nucleotides. Isotope : a variation of an element that differs in the number of parts it possesses, more specifically the number of subatomic particles called neutrons. Radiocarbon dating : a technique that measures the age of an object containing carbon by measuring the decay of the radioactive isotope carbon

Why Anthropology?

Dating is nothing more than ordering time. Time is the quintessential sorter of events. All living beings go through life being on occasion acutely aware of its transient yet eternal, ceaseless yet tenacious quality. Time is the omnipresent judge that indicts all life for existence and condemns it to death. Thus, for the greatest portion of human history, time was seen in terms of an individual or series of lifetimes, with a clear beginning and a clear end.

Paleoanthropology , a subdiscipline of anthropology, is the study of extinct primates. While the majority of researchers doing this kind of work are anthropologists, paleontologists within the discipline of geology may also study fossil primates. The primary method used by paleoanthropologists is the analysis of fossil remains. However, they increasingly rely on other scientific disciplines to gain a better understanding of the environmental forces that played a role in our evolution, as well as the formation of the fossil record. A variety of disciplines are involved in helping to reconstruct ancient environments and biological communities.
