PDF-(BOOS)-The Last Neanderthal: The Rise, Success, and Mysterious Extinction of Our Closest

Scientists have long known that the popular image of the Neanderthal as a primitive hairy heavily browed clubwielding brute is not supported by the fossil evidence But to date no such consensus has existed on the riddle of Neanderthals disappearance The Last Neanderthal written by one of the most respected authorities he subject and supported by a dazzling wealth of material paints the first full portrait of the most familiar and haunting of human relatives Drawing on the latest findings and sophisticated new techniques of analysis Ian Tattersall marshals the best available evidence to unravel the mysteries of the Neanderthals who they were how they lived how they succeeded for so long Drawing on his own research and the work of others Tattersall takes on the most fascinating question of all what happened to them This revised edition is fully updated to include information on Tattersalls recent survey of all known Neanderthal fossils and cuttingedge work with Neanderthal DNA. Evolutionary lifehistory theory seeks to explain crossspecies differences in these variables and the covariation between them That provides the foundation for a hypothesis that a novel role for grandmothers underlies the shift from an apelike ancest scouts out from the nest to search separately for food. By fanning out across a larger area while the rest of the colony stays home, they encounter more prey and enemies. Yet colonies that rely on sco Credits to Vanessa Patel for some of the slides.

The story of Neanderthal man. Was he our direct ancestor, or was he perhaps a more alien figure, genetically very different? This title brings us into the Neanderthal\'s world, his technology, his way of life, his origins and his relationship with us.
