Answer:
Human evolution is about the origin of human beings. All humans belong to the same species, which has spread from its birthplace in Africa to almost all parts of the world. Its origin in Africa is proved by the fossils which have been found there.[1][2][3]
Explanation:
The term 'human' in this context means the genus Homo. However, studies of human evolution usually include other hominids, such as the Australopithecines, from which the genus Homo had diverged (split) by about 2.3 to 2.4 million years ago in Africa.[4][5] The first Homo sapiens, the ancestors of today's humans, evolved around 200,000 years ago.[6]
It was known for centuries that man and the apes were related. At heart, their anatomy is similar, despite many superficial differences. This was the reason why Buffon and Linnaeus, in the 18th century, put them together in one family. Charles Darwin's theory of evolution says that such basic structural similarity comes from the common origin of the group. The apes and man are close relatives, and are primates: the order of mammals which includes monkeys, apes, lemurs and tarsiers.
The great apes live in tropical rainforests. It is thought that human evolution started when a group of apes (now called the australopithecines) began to live more in the savannah. A savannah is more open, with trees, shrubs and grass. This group started walking on two legs. They began to use their hands to carry things. Life in the open was different, and there was a big advantage in having better brains. Their brains grew larger, and they began to make simple tools. This process began at least 5 million years ago. We have fossils of two or three different groups of walking apes, and one was the ancestor of humans.
The biological name for "human" or "man" is Homo. The modern human species is called Homo sapiens. "Sapiens" means "thought". Homo sapiens means "the thinking man".
Paleoanthropology looks at ancient human fossils, tools, and other signs of early human life. It began in the 19th century with the discovery of a skull of "Neanderthal man" in 1856.
Answer:
The evolutionary process is indeed complex, but also vital to our understanding of our place in the natural world. In the following essay, I will explain, in detail, each facet of evolution and how it pertains to human beings and to our genetic make up. I will talk about how evolution is interwoven into our own nature as evident by the many fields of anthropology, I will talk about the perceptive minds who simultaneously discovered evolution, then I will move onto genetics, first talking about the cells and molecules than moving onto genotypes and phenotypes. Finally, I will finish this paper on the larger scale forces of evolution and how it materialized in our own variation. Evolution is the gradual change genes and traits in any given population over the span of thousands to millions of generations (Stanford 2). . Biological Anthropologists study human beings in their biological sphere through the prism of evolution and call it Physical Anthropology (Stanford 2). Many other anthropologists study anthropology, or the study of comparing culture of humankind, through a different aspect of evolution. Such as paleoanthropologists study human fossils (Stanford 5), ethnologists, who study of how past peoples lived their daily life (Stanford 4), cultural anthropologists, who study the human societies of the past. Each of the anthropological sects used evolution to teach us about different aspects of our past.
