        The skeletons, of a boy and a young woman, standing a few inches over four feet, have orangutan-length arms but human-shaped hands. Changes to the legs and pelvis suggest that the creatures spent much of their time upright, although their feet are primitive. They have small, human like teeth but an ape-size brain case. Add your comment on item 1212

        Advocates of this theory argue that the great leap forward occurred sometime between 50-40 kya in Africa or Europe. They argue that humans who lived before 50 kya were behaviorally primitive and indistinguishable from other extinct hominids such as the Neanderthals or Homo erectus. Proponents of this view base their evidence on the abundance of complex artifacts, such as artwork and bone tools of the Upper Paleolithic, that appear in the fossil record after 50 kya. They argue that such artifacts are absent from the fossil record from before 50 kya, indicating that earlier hominids lacked the cognitive skills required to produce such artifacts. Add your comment on item 4747

        Jared Diamond states that humans of the Acheulean and Mousterian cultures lived in an apparent stasis, experiencing little cultural change. This was followed by a sudden flowering of fine toolmaking, sophisticated weaponry, sculpture, cave painting, body ornaments, and long-distance trade.[11] Humans also expanded into hitherto uninhabited environments, such as Australia and Northern Eurasia.[11] Add your comment on item 4848

        The Great Leap Forward was concurrent with the extinction of the Neanderthals, and it has been suggested that Cro-Magnon interaction with Neanderthals caused this extinction. Add your comment on item 4949

        According to this model, the emergence of anatomically modern humans predates the emergence of behaviorally modern humans by over 100 kya. Add your comment on item 5050

        Proponents of the continuity hypothesis hold that no single genetic or biological change is responsible for the appearance of modern behavior. They contend that modern human behavior is the result of sociocultural and sociobiological evolution occurring over hundreds of thousands of years. Add your comment on item 5353

        Continuity theorists base their assertions on evidence of modern behavior that can be seen in the Middle Stone Age (approximately 250 - 50 kya) at a number of sites in Africa and the Levant. For example, a ritual burial with grave goods at Qafzeh is Middle Stone Age (MSA) having been dated to 90 kya. The use of pigment is noted at several MSA sites in Africa dating back more than 100 kya. Add your comment on item 5454

        Continuity theorists believe that what appears to be a technological revolution at the onset of the Upper Paleolithic is most likely a result of increased cultural exchange resulting from a growing human population. Some continuity theorists also argue that the rapid pace of cultural evolution during the Upper Paleolithic transition may have been triggered by adverse environmental conditions such as aridity arising from glacial maxima.[1] They further dispute that anatomical modernity predates behavioral modernity, stating that changes in human anatomy and behavioral changes occurred stepwise.[5] The findings of Curtis Marean and his colleagues of fishing and symbolic behavior dating to 164,000 years ago on the southern African coast strongly support this analysis.[12] Add your comment on item 5555
