A Theme In Human Evolution - Research Paper Example An exanimation of the fossil records for the hominids can reveal much information on the early forms of the present creatures. The study of human remains did not feature until the nineteenth century when archaeologists realized that the culture and the morphology of early man could be revealed by the remains and the tools that were found buried with these remains (Greene, 11). A comparison between the morphology of the different fossils can be made to provide an insight into the relationships that occur between populations of organisms at different stages in the evolution process. Much information regarding the human culture could be obtained through the study of such remains. It has been noted that by studying the bone morphology of the fossils â€Å"one can understand the nutritional status, diet, disease processes, factors affecting mortality and life expectancy, biological responses to environmental stressors and aging of our ancestors† (Seth, 19). The teeth of animals wil l be related to the kinds of food that they consume. The herbivorous animals feed on vegetation and have many large molar teeth for chewing the fibrous foods. On the other hand, carnivorous animals like lion have large canine teeth that are used for killing and tearing the meat of their prey. The early hominids had the ape-like U-shaped dental arcade whereas the modern, man has a parabolic dental arcade. These early hominids and the modern man have the same dental formula of 2.1.2.3= 32.   This means two incisors, one canine, two premolars, and three molar teeth on both sides of the upper and lower jaws. However, there is a difference in the teeth structure and size between the early hominids and the modern man. This has been caused by the difference in the kinds of food that have been consumed by man at different stages of evolution. The early hominids were mainly herbivorous and had large molars for chewing the high roughage content foods.
