As a result led an arboreal way of life characterized good eye precision, a hand grip and padded feet with claws to enable climbing.
The first primates were Prosimians whose niche was during the Paleocene Epoch. Prosimians faced global extinction of plants and animals that lacked adaptions to survive in the changing environment and had to adapt to complete the versatile ecological niche (Butzer, 1977). The early Prosimians were relatively small in size, they had a grasping hand and feet that were adapted to climbing trees and efficiently manipulated objects. At this stage they were developing stereoscopic vision. However, the Prosimians became extinct by the end of the Eocene Epoch and gave way to the anthropoids that existed during the Oligocene.
The Oligocene was characterized by regional climate shifts that definitely influenced the direction of evolution (O’Neil, 2003). The climate at the time created a favorable environment for growth of fruits and seed plants that the anthropoids feed on. However, they still lived on trees. Due their environment and feeding habits, they had fewer teeth, larger brain capacity and a more defined stereoscopic vision as compared to the Prosimians.
The Miocene Epoch was the next Epoch after the Oligocene. It was characterized by the movement of tectonic plates that created mountain chains. This changed the weather patterns, whereas the progressive global cooling and drying was still in force. Eventually, polar ice caps reduced the amount of water in the oceans lowering the sea levels. A land reconnection occurred between Africa and Asia, providing a migration route for primates and other animals (Williams, 2001). Tropical forests in South Asia and East Africa replaced the dry grasslands and woodlands providing a strategic environment for the survival of primates.
The hominoids evolved during this period as primate

It is this paper’s position that the human race came about as they are now through the process of evolution. The author believes that living organisms today evolved through the process of natural selection and this has been the key to the survival of living things on earth.
The Human Rights Act (1998), which is a fundamental portion of UK law today, stipulates that every individual has the right to a fair trial in all situations and circumstances2 Article 6 provides the guarantee that all people must have a right to a fair trial.
Evidence of the evolvement of Homo sapiens from Homo erectors has mainly been provided through analysis of human fossils that have shown that certain changes did occur in the brain and body size, diet, movement The changes in the millions of stone tools and footprints have also helped in the understanding of the evolution of Homo sapiens.
According to Heinrich, before agricultural evolution, humans spread throughout the globe, Therefore surviving in the different habitats did not only depend on the specific genetic configuration, but depended also on large body of cultural information transmitted across the groups, abilities, and other skills that no human could have comprehended alone.
