Analytical Essay (Hominid Species Evolution)

Hominid Species can be defined as "any of the modern or extinct bipedal primates of the family Hominidae to the extent of Homo Sapiens, present day humans" (2009). These species date back to a time frame within 23 million years ago and have all evolved significantly due to physical changes in the environment and natural selection. Some factors of the hominid species evolution however, are determined by the increase of intelligence over time and therefore the use of tools caused them to evolve undue to nature. Through the use of skull reconstructions, brain and brawn statistics and canine evidence, various theories are circulating within the science community to suggest reasoning for the

Teeth also provide incomplete evidence as they are prone to falling out and being misplaced. It would be unidentifiable to measure evolution over millions of years through teeth that could have changed many times as opposed to an entire bone that requires millions of years to dramatically transform.
Due to the reliability of the skull structure evolution, the Saint Stephens students used this factor more significantly than the canine evidence to suggest the most possible hominid species phylogeny.
The most accepted human phylogeny currently circulating within the science community today is the theory that homo sapiens (modern day humans) evolved from a long line of apes and bipedal primates. This is due to the similarities of bi-pedal behaviour, diet and habitat. Another famous theory of evolution is the hypothesis of regional continuity whereby a species lived in two continents at once therefore evolving separately according to their experiences and environments. This theory is supported by the phylogeny created by Saint Stephens students as more than one identical group of species appeared to have evolved separately. Although evidence mostly supports our ape-like ancestry tree, the individual's interpretation always causes dispute and opposition to the facts present. These interpretations are often opposed by a religious, spiritual or cultural influence and deemed the scientific proposition untrue, therefore creating the possibility for yet another theory of
