Unformatted sample text from the term paper:
tugenensis is believed to be one of human beings closest evolutionary ancestors. Fossilized remains of the species were first found in the Lukeino Formation in Kenya in the
Tugen Hills in 2000. These remains were dated using radioisotopes and in comparison to the age of sedimentary crystals above and below the fossils. To date, although
numerous specimens of the species have been found that are believed to represent distinct individuals, these specimens are isolated body parts such as mandibles, symphysix, teeth and various fragments from
other body parts. They thus only a very truncated view of the species. The species is believed by some, however, to be one of the earliest hominins that
walked upright on two feet. The intent of this paper is to provide an overview of what is known about this species and the place that it holds in
relationship with modern man. With these assumptions in mind, a small collection of key articles on this species will be reviewed and summarized in order to accomplish
this purpose. Findings
Mankinds evolution has been marked by distinct physiological changes as well as distinct cultural and technological changes. Present day hominids are a lineage which diverged from the ape
species millions of years ago. Through the succeeding years in prehistory there were, at any given time, several species of primates living concurrently which displayed the hominid characteristics of
standing erect and walking upright (Lemonick et. al.). It has been only since the disappearance of the Neanderthals thirty thousand years ago that modern day Homo sapiens have been
