Six to seven million years ago Homo sapiens oldest common ancestor roamed the earth, specifically in the north-central region on the continent of Africa. This ancestor is known as Sahelanthropus tchadensis (Tattersall). They are accepted to have common lineage due to their terrestrial bipedalism, forward positioned foramen magnum, the broad and flat facial structure, and the smaller canines separating it from the very similar ape family (Tattersall). Unfortunately the genus Homo has not had much luck with their population sizes considering eight out of nine species belonging to it have gone extinct (Tattersall). This may be why Homo sapiens do so well with population growth; evolution of our genus found the problem and solved it but this problem may have been way to overly corrected. 200,000 years ago humans originated in the continent of Africa (New World Encyclopedia). Human population has been steadily increasing over time and the rate of this increase has jumped drastically. Over the 200,000 years that humans have been around the population has sky rocketed just in the last 60 years. In 1950 the world population was 2,557,628,654 since then our population has almost tripled (United States Census Bureau). If you think about how long it took us to get to that 2.5 billion and how much we jumped in a small fraction of that time it is easier to fathom our population growth dilemma. There are four main factors that are taking into consideration when accessing population…
