Document Summary

Our nearest relatives: hominins and other great apes. Studying human evolution, migrations, and race fossils and morphology. Archaeology behaviors and social organization structures and material evidence of culture language, origin and variations. Humans and other great apes share morphological features: Changes in structure and use of arm and shoulder. Humans and african great apes share additional morphological features: Closest relations: chimpanzees are the closest living relative to humans. The split of the hominins: species that are more closely related to humans that to chimps are called hominins. Morphological features are used to tell us how they lived and what they were like. Structures of shoulders, arms = use of hands for tools. Brain size = ability for language, social organization. The hominids split from the chimpanzee lineage about 6-7 million years ago. Ardipithecus (2 spp. 4. 4 mya) among the oldest hominin fossils. Facultatively bipedal (could switch between tree-dwelling and walking upright)
