ANT101H5 Lecture Notes - Lecture 12: Homo Heidelbergensis, Homo Erectus, Mastoid Part Of The Temporal Bone
Document Summary
40,000 or 15,000ya in australia to the present. Morphological characteristics: distinct chin, round skull, flat vertical face, a higher forehead, pyramidal mastoid process, are generally less robust and have thinner brow ridges. Speciation: the process of separation into a new species, often based on geological isolation. Biological species: populations that can interbreed with each other and produce fertile offspring. Paleospecies: species defined by fossil evidence from a long time ago, who may or may not interbreed. They look so different that we say that they"re a different species. Top model: shows the gradual process of evolution. There is an early group of homo, some go extinct. Homo erectus branches out and eventually becomes early homo heidelbergenis. Bottom model: shows each group as a separate species, where there is a rapid evolutionary change through transitional species which are not yet discovered. Transition models: process of evolution from premoderns to homo sapiens. Regional continuity: multi-regional evolution model: only uses fossil evidence, no.
