The initial evolution of humans occurred on which continent?

Explanation : Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans. Evolution creates variations to allow the living organism to adjust according to the living environment. The human traits continuously vary with the changing environment and it creates variations. 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 100,000 years. Humans are primates. Physical and genetic similarities show that the modern human species, Homo sapiens, has a very close relationship to another group of primate species, the apes. Humans and the great apes (large apes) of Africa chimpanzees and gorillas share a common ancestor that lived between 8 and 6 million years ago.
