Human evolution is the evolutionary process that led to the emergence of anatomically modern humans , beginning with the evolutionary history of primates in particular genus Homo and leading to the emergence of Homo sapiens as a distinct species of the hominid family , the great apes. This process involved the gradual development of traits such as human bipedalism and language , [1] as well as interbreeding with other hominins , which indicate that human evolution was not linear but a web. The study of human evolution involves several scientific disciplines, including physical anthropology , primatology , archaeology , paleontology , neurobiology , ethology , linguistics , evolutionary psychology , embryology and genetics. Human evolution from its first separation from the last common ancestor of humans and chimpanzees is characterized by a number of morphological , developmental , physiological , and behavioral changes. The most significant of these adaptations are bipedalism, increased brain size, lengthened ontogeny gestation and infancy , and decreased sexual dimorphism.

The origin of modern humans has probably been the most debated issue in evolutionary biology over the last few decades. Our evolutionary history is written into our genome. The human genome looks the way it does because of all the genetic changes that have affected our ancestors. The exact origin of modern humans has long been a topic of debate. Modern humans originated in Africa within the past , years and evolved from their most likely recent common ancestor, Homo erectus. Our species is the only surviving species of the genus Homo but where we came from has been a topic of much debate.

This the nearly 2-million-year-old skull of a young boy found in the Malapa cave. Some scientists are arguing that its species is the most direct ancestor of what would evolve into the genus containing humans. Almost 2 million years ago in what is now South Africa, a boy and a woman fell to their deaths through a hole in the ground. The pair had tumbled through the collapsed roof of an underground cave. A storm soon washed their bodies into a lake or pool within the cave. Wet soil rapidly hardened around the bodies, protecting their bones.

The question of where we humans come from is one many people ask, and the answer is getting more complicated as new evidence is emerging all the time. For most of recorded history humankind has been placed on a metaphorical, and sometimes literal, pedestal. Sure, modern humans were flesh and blood like other animals. But they were regarded as being so special that in the Linnaean taxonomy that prevailed well into the second half of the 20th century they were given their own family, the Hominidae. This distinguished them from the Pongidae, the separate family used for the three African great apes the common chimpanzee, bonobo and gorilla plus the orangutan from Southeast Asia. In the 19th century the only evidence available for determining the closeness of the relationship between any two living animals was how similar they were in terms of what the naked eye could tell from their bones, teeth, muscles and organs.

A new paper challenges the traditional idea that our species evolved from a single population in one region of Africa. Scientists are sure that Homo sapiens first evolved in Africa , and we know that every person alive today can trace their genetic ancestry to there. It has long been thought that we began in one single east or south African population, which eventually spread into Asia and Europe. But it seems that things were more complex than that - the link between those hominins and the humans on Earth today is neither straight nor simple.

Evolution of modern humans

Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years. One of the earliest defining human traits, bipedalism -- the ability to walk on two legs -- evolved over 4 million years ago. Other important human characteristics -- such as a large and complex brain, the ability to make and use tools, and the capacity for language -- developed more recently. Many advanced traits -- including complex symbolic expression, art, and elaborate cultural diversity -- emerged mainly during the past , years. Humans are primates.

Humans first evolved in Africa, and much of human evolution occurred on that of early humans who lived between 6 and 2 million years ago come entirely.
