Document Summary
Primitive : recall: there is no such thing as higher or lower organisms (ie. primitive or. Population : recall: populations comprise individuals in the same species that live in the same area; the use in the current textbook may be better described as a community" (ie. p 226) The origin of the human lineage is a late event in earth history. At the end triassic period, therapsids, which were a group with mammalian traits, mostly disappeared. One therapsids lineage evolved & diversi ed, ultimately constituting mammals. The cainozoic era saw a spectacular mammal radiation, following extinction of the dinosaurs (except birds). Early triassic period: therapsids: warm blooded, fur-covered synapsids". Late triassic, early jurassic period: first mammals; dinosaurs rule. End of cretaceous: dinosaurs" extinct; mammal radiation. To understand how modern humans evolved, one must be familiar with the geological, climatic, & biological conditions under which the descent with modi cation occurred. Earth has changed over time: continental drift.
