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 the only Homo species (Lemonick et. al.). There were, however, many evolutionary steps preceding our arrival at the Homo genus that
are worthy of note. Scientists recognize four important milestones in the evolution of hominids when they separated from the apes around six million
to four million years ago. The first milestone was becoming bipedal, walking upright on two legs instead of four (Lemonick et. al.). The second milestone was when hominids
began to make tools of stone instead of merely using unmodified stones that they found lying around. The third milestone was when humans began eating meat (Lemonick et. al.).
Contemporary belief is that the eating of meat gave a high fat diet which led to increased brain size and concurrently they began migrating out of Africa (Lemonick et.
al.). The last major milestone was the development of abstract thought which provided for language, art and advancing technology (Lemonick et. al.).
Five million years ago the oldest known hominid fossils were of the species Australopithecus afarensis and were dated at three and six-tenths million years old (Lemonick et. al.). Two
