IgeoNews's video: The ancestors of man on Earth IgeoNews

THE ANCESTORS OF MAN ON EARTH 200 million years ago the beginning of mammalian development took place on Earth. To reach our closest ancestor, the evolution of man has gone through different stages. We distinguish between two main genres: -The Australopithecus They are the ancestors of the genus Homo. They are characterized by bipedal. The prime example of this genre is represented by the famous Lucy. Its place of origin is Africa. Disappear as a result of climate crisis about 2.8 million years which led to desertification Savannah ago. Main species of this genus: - Australopithecus anamensis: 3.9 to 4,200,000 years, in Kenya. Cranial capacity was 300 cc - Australopithecus afarensis: 3.9 to 3,000,000 years, in Ethiopia. Cranial capacity of 375-550 cc. The famous Lucy. - Australopithecus africanus: 3 million years ago in South Africa. Cranial capacity of 480 cc - 520 cc. -The Genus Homo. The evidence indicates that there were at least four species of these hominids shared continent and region. - Homo habilis: 2,5 to 1.44 million years in Tanzania (Africa). It is the first species of the genus Homo, "handy man." Cranial capacity to 650cc - 850cc. - Homo ergaster: Makes about 2 million years, in Kenya. Brain 850 cm ³. Making use of your bipidismo left the African continent to Europe and Asia. - Homo Erectus: 1.8 million years and 300,000 years. It was the first hominid big and heavy as humans. And travelers were the first hominids from Africa to Eurasia expand. Remains have been found in Beijing (China), Indonesia, and Atapuerta (Spain). 700cc increased cranial capacity - 1300 cc. - Homo heidelbergensis: It is an extinct species of the genus Homo. Appeared more than 500,000 years ago and lasted until at least 250,000 years ago, in Heidelberg, Germany. Great Skulls 1,350 cc - Homo neanderthalensis: in Western Europe and parts of Asia, makes 230000-29000 years. There is a direct ancestor of modern man but it comes from a branch parallel to the evolutionary tree. Cranial capacity 1500 c. - Homo sapiens: Homo genus is more diverse. In Asia and Africa. Since the extinction of the Neanderthals, some 30,000 years ago, Homo sapiens is the only surviving species of the genus Homo.
