Answer 1

Human Evolution

Human evolution is the lengthy process of change by which people originated from apelike ancestors starting nearly five million years ago. The modern scientific study of human evolution is called paleoanthropology. A subfield of anthropology, this discipline searches for the roots of human physical traits, culture, and behavior. It attempts to answer questions: What makes us human? When and why did we begin to walk upright? How did our brains, language, art, music, and religion develop? By approaching these questions from a variety of directions, using information learned from other disciplines such as molecular biology, paleontology, archaeology, sociology, and biology, we continue to increase knowledge of our evolutionary origins.

Most cultures throughout human history have myths, stories, and ideas about how life and culture came into existence. Although the current theory of evolution, based on the ideas of Charles Darwin, is accepted by a majority of scientists in our time, it is important to remember that many earlier ideas were recognized. Darwin's books, On the Origins of the Species by Natural Selection (1859) and The Descent of Man (1872), expressed his theory of evolution and revolutionized the study of life and human origins.
Darwin presented evidence showing that natural species including humans have changed, or evolved, over long spans of time. He also argued that radically new forms of life develop from existing species. He noted that all organisms compete with one another for food, space, mates, and other things needed for survival and reproduction. The most successful individuals in this competition have the greatest chance of reproducing and passing these characteristics on to offspring. Over hundreds of thousands of generations, one form of life can evolve into one or more other forms. Darwin called this process natural selection.

Answer:

• Here is your answer..

Explanation:

It is true that human evolution began 7 - 10 million years ago. Theories like the 'The Origin of Species' by Charles Darwin suggested that humans emerged from the apes who lived in the African regions which was confirmed by the study of the 3-4 million old Australopithecus fossils. Genetic studies and studies of the fossil evidences by methods like radio-dating, etc. has confirmed these theories. 

Studies by paleo-anthropologists on different types of fossils from different regions have led to the theory of evolution of man from apes which have been recorded in the evidence books.
