Document Summary
Key physical traits, why they emerged(and their advantages). The early hominins uncertainties remain: particularly when we go further back in time. Some species are relatively well represented in terms of fossils some not so much. Mossaic evolution:remember that different complexes in organisms gave independent evolutionary histories and have changed at different times/rate in fossil records(pg20). Changes in dental morphology, bipedalism and the brain didn"t happen all at the same rate not all happening together. The text and hominin versus hominid (genetics and morphology) Hominid: a term that is morphologically inspired. Hominin: a term that re ects newer genetic understandings(ie closer genetic relationships between human and some non human primates) Why did your text decide to go with hominid (especially ve that so much of recent pas literature) Seeing the footprints not just the bones helped with understanding gait. Changes in pelvis help ensure staying upright.
