2. AUSTRALOPHITEUS AFRICANUS

3. The first fossil remains: the cranium of a child known as the child of Taung. They were discovered in 1924 ,in Taung, South Africa.

4. His cranial capacity is 480 cm³ to 520 cm³, far below the human current being. The face is shorter. The mandible is advanced with respect to the jaw.

5. A. africanus had a bipedal running, but still retained arboreal habits. His weight ranged between 33 and 67 kg with a height of 1.50 m. The absolute ages are difficult to identify the characteristics of the deposits. It is believed than 2 to 3 m.a.

6. Australopithecus afarensis The species name is Australopithecus afarensis . Australopithecus afarensis is an extinct hominid of the subtribe hominin that lived between 3.9 and 3 million years ago. Texture was thin and graceful, and is believed to live only in East Africa. Remains of this species have been found in Africa. East Africa was its distribution area.

7. Australopithecus afarensis

11. Map distribution area

13. Homo habilis (2.5-1.4 million years).

21. HOMO ERGASTER

27. HOMO ERECTUS

40. Homo neanthertalensis

42. The area of distribution Atapuerca site

43. What was the ecosystem where they lived? It was a species well adapted to cold weather thanks to its broad and elongated skulls, their robustness, short and broad nose. It is known that they lived in organized groups that were composed of about 30 members.

44. Cranial volume/ Height/ Features Characteristics: strong skeleton, wide pelvis, short legs, barrel chest, low forehead, jaws without menthol and large cranial capacity —1.500 cm³—

45. Diet Fossil remains provide evidence that they moved in small groups possibly occupying areas seasonally and subsisting by hunting big-game such as reindeer. Animal bones found with Neanderthal remains are mostly cold adapted species such as reindeer, bison, elk, arctic fox, lemming and mammoth . These Neanderthals had diets similar to nonhuman carnivore.

46. Industry type lithic

47. Period existed It appears about 200,000 years and disappeared 35,000 years ago, during the Pleistocene. His disappearance could be due to lack of adaptation to the Homo sapiens. They coexisted with Homo sapiens .
