Archeological Features, Artifacts and Ecofacts Essay - 40

Archeological Features, Artifacts and Ecofacts - Essay Example Analysis of the archeological site is done through key stages. The archeological sites entail the places where proof of past human presence can be collected. The evidence includes skeleton remains of the human ancestors, artifacts objects, and ecofacts elements. Sites are developed through formation processes. For example, dead bodies can be ceremonially buried, and tools can be lost. Site preservation is done by the natural process. The ash from a volcano or the silt from flood water can cover objects, and thus preserve them for several years. Sites can also be found by the natural process of erosion. The Olduvai Gorge located in Tanzania was exposed through erosion (Gilman, 2012). Archaeologists apply several techniques. The archeologists apply experimental replication to analyze tool artifacts. The process aims at authentically redeveloping the ancient artifacts, and hence determines the process of making the tool. The date of the specimen or archaeological site is done through ra dioactive decay technique. The technique analyses the radioactive isotopes of common elements like carbon, uranium and potassium. Identifying the sex skeleton is done by the sex dimorphism technique. For instance, the male human skeleton is always larger, rougher and denser than the female skeletal bones. The Upper Paleolithic period is illustrated through drastic changes in the human culture, especially in the Europe, Asia and African regions. Greatly, the changes are developmental as illustrated by the anatomically modern man of Africa. Superior tools were identified in Africa. One example involves the stone blade tools aged 90,000 years, which were found in Katanga, Zaire. Polished bone tools aged 77,000 years were found inside the Blombos Cave, South Africa (Robert & Wendy 2011). The tools illustrate technology explosion in the area of stone and bone tool  development.
