Short Note on Human origin and human wandering (150 words)
Answers
Answer:
Most of what we know about the origin of humans comes from the research of paleoanthropologists, scientists who study human fossils. Paleoanthropologists identify the sites where fossils can be found. They determine the age of fossils and describe the features of the bones and teeth discovered. Recently, paleoanthropologists have added genetic technology to test their hypotheses. In this article, we will tell you a little about prehistory, a period of time including pre-humans and humans and lasting about 10 million years. During the Prehistoric Period, events were not reported in writing. Most information on prehistory is obtained through studying fossils. Ten to twelve million years ago, primates divided into two branches, one included species leading to modern (current) humans and the other branch to the great apes that include gorillas, chimpanzees, bonobos, and orangutans. The branch leading to modern humans included several different species. When one of these species—known as the Neanderthals—inhabited Eurasia, they were not alone; Homo sapiens and other Homo species were also present in this region. All the other species of Homo have gone extinct, with the exception of Homo sapiens, our species, which gradually colonized the entire planet. About 12,000 years ago, during the Neolithic Period, some (but not all) populations of H. sapiens passed from a wandering lifestyle of hunting and gathering to one of sedentary farming, building villages and towns. They developed more complex social organizations and invented writing. This was the end of prehistory and the beginning of histor
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]
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.
