The word anthropology is derived from two Greek words: anthropos meaning "man" or "human"; and logos, meaning "thought" or "reason." Anthropologists attempt, by investigating the whole range of human development and behavior, to achieve a total description of cultural and social phenomena.The science of anthropology is divided into two major disciplines, physical anthropology and cultural anthropology.However, paleontology as a whole encompasses all life, from bacteria to whales.Paleontology does not usually deal with artifacts made by humans.Professor Willard Libby produced the first radiocarbon dates in 1949 and was later awarded the Nobel Prize for his efforts.Radiocarbon dating works by comparing the three different isotopes of carbon. A fossil is defined as any trace of a past life form.
Some paleontologists do study the fossil record of humans and their relatives.
It is possible to tell the number of years ago a particular rock or archeological site had been formed.
Two broad categories of classification methods are relative dating and absolute dating.
This is a method that does not find the age in years but is an effective technique to compare the ages of two or more artifacts, rocks or even sites.
It implies that relative dating cannot say conclusively about the true age of an artifact.
Absolute dating, on the other hand is capable of telling the exact age of an item using carbon dating and many other techniques that were not there in earlier times.
