History Of Human Evolution Essay

As everyone knows, the history of human evolution originated from more than five million years ago (Pickrell, 2006). Human is the most intellective living being on the Earth, even in the developed universe. With the development of human being, the beginning of human started to be discovered. This essay will focus on the evolution history of human being. It will explain three most significant time slices of human evolution.

The origin of human beings has to trace back to the chimps which lived in millions of years ago. About six to eight million years ago, people’s ancestor split from chimp (Pickrell, 2006). In The Origin of Species, which is published by Darwin in 1859, African apes were thought as the ancestor of human beings. And in the next

70 years of research, the discovery of“Taung child” proved this hypothesis (Pickrell, 2006). It is the first step of human’s evolution. The ancestors of human started their trip of developing their race. Then, the branch of human beings began to walk with two legs (Pickrell, 2006). For example, the fossil of “Lucy” is the most intact one of early ape-man. The existence of “Lucy” showed the history of two legs walking people. They were called “Orrorin tugenensis” and lived in the forests or on the savannah (Pickrell, 2006). During the first period of evolution, the earliest hominids had lived in the Earth, when their brains have not developed and ate the roots of plants and the vegetations only.
Two and a half million years ago, some hominids started to use tools and fire to get food and continued to develop their brain volume (Pickrell, 2006). In this period, the primitive society has had a basal structure. The hominids ate the raw or cold food instead of the vegetations. The change of food made their face have altered, which let them look more like modern humans. It also caused the development of the brain. The hominids learnt to think and migrated to the areas where were fitter to live (Pickrell, 2006). However, it is still a process of the whole human’s evolution. During the latter part of this period, the fire appeared in the hominids’ society. They began to heat food and made tools to assist their daily life (Pickrell, 2006). About 150 thousand years ago, the original humans had had the ability to speak and started to use simple symbols and words. It is a meaningful progress of human’s evolution. The appearance of languages and words meant that primitive human society has opened a new era. At this point, the hominids almost have completed their evolution and become more similar to the modern humans (Pickrell, 2006).
The period which is another important time point of human evolution is the “Great leap forward”.

About fifty thousand years ago, the human cultures started to be more and more similar to modern culture. The hominids killed animals not only to feed themselves but also for the production of clothing (Pickrell, 2006). The hominids had the sense of shame. They used hides to cover their body. Besides, the hominids have the thought to bury their companions (Pickrell, 2006). It is an idea of group or family. With the final formation of human society, people developed and valued quickly. The oldest cave painting had more than thirty-three thousand years’ history (Pickrell, 2006). It is the proof of original humans’ pursuit of art. Almost ten thousand years ago, the systematic agriculture appeared, developed and spread with an amazing speed (Pickrell, 2006). Humans started to plant cereal and raise and train livestock. After that, the Bronze Age carried on the Stone Age (Pickrell, 2006). The change of tool materials helped people have higher efficiency when they were working. At the same time, the first recorded human culture appeared in Mesopotamia (Pickrell, 2006). Until this time point, human beings finished their evolution from ancient apes to modern humans. The process, which had experienced more than hundreds million years, was the most wonderful evolution on the

Earth.
To sum up, the evolution of human is a long process. During the evolution, the humans’ ancestor migrated to better lands and developed abilities constantly. It is an amazing history. Human beings have experienced countless survival of the fittest and have become the highest animals on the Earth. The time and tide gave people the best answer of living beings.
