| Name | Definition |
|---|---|
| Pliocene Epoch | The 5th epoch of the Cenozoic era, dating from 5 million to 1.7 million ya |
| Pleistocene Epoch | The 6th epoch of the Cenozoic era, dating from 1.7-0.01 mya |
| Oldowan Tradition | The oldest known stone tool culture |
| Endocast | A cast of the interior of the brain case used in analyzing brain size and structure. |
| Acheulian Tradition | The stone tool culture that appears first with Homo erectus and is characterized by the development of hand axes and other bifacial tools. |
| Archaic humans | Specimens of Homo with brain size close to that of modern humans but with differently shaped skulls. There is considerable controversy over whether they are an earlier form of Homo sapiens or represent different species. |
| Prepared core method | An efficient method of stone tool manufacture in which a stone core is prepared and then finished tools are removed from it. |
| Mousterian tradition | The prepared-core stone tool technology of the Neaderthals. |
| Anatomically modern Homo Sapiens | The modern form of the human species, which dates back 130,000 years or more. |
| Upper Paleolithic | The Upper Old Stone Age, a general term used to collectively refer to the stone tool technologies of the anatomically modern Homo sapiens. |
| Lower Paleolithic | The Lower Old Stone Age, a general term used to collectively refer to the stone tool technologies of Homo habilis/Homo rudolfensis and Homo erectus. |
| Middle Paleolithic | The Middle Old Stone Age, a general term used to collectively refer to the stone tool technologies of archaic humans. |
| African Replacement Model | The hypothesis that modern humans evolved as a new species in Africa between 150,000 and 200,000 ya and then spread throughout the Old World, replacing preexisting archaic human populations. |
| Multiregional evolution model | The hypothesis that modern humans evolved throughout the Old World as a single species after the first dispersion of Homo erectus out of Africa. |
| Regional coalescence model | A variant of the multiregional evolution model of the origin of modern humans that suggests the transition from archaic to modern humans resulted from the coalescence of generic and anatomic changes that took place in different place at different times, |
| Primary African origin model | A variant of the multiregional evolution model of the origin of modern humans that suggest most of the transition from archaic to modern humans took place first in Africa and then spread throughout the rest of the species across the Old World by gene flow |
| Regional continuity | The appearance of similar traits within a geographic region that remains over a long period of time. |
| Sedentary | Settled in one place throughout most or all of the year. |
| Paleopathology | The study of disease in prehistoric populations based on analysis of skeletal remains and archaeological evidence. |
| Carry capacity | The maximum population size capable of being supported in a given environment. |
| Natural increase | Number of births minus the number of deaths |
| Life expectancy at birth | A measure of the average length of life for a newborn child |
| Life Table | A compilation of the age distribution of a population that provides an estimate of the probability that an individual will die by a certain age, used to compute life expectancy. |
| Zoonose | A disease directly to humans from other animals. |
| Epidemic | A pattern of disease rate when new cases of a disease spread rapidly through a population. |
| Endemic | A pattern of disease rate when new cases of a disease occur at a relatively constant but low rate over time. |
| Pandemic | A widespread epidemic that affects a large geographic area, such as a continent. |
| Epidemiologic transition | The increase in life expectancy and the shift from infectious to noninfectious disease as the primary cause of death. |
| Secular change | A change in the average pattern of growth or development in a population over several generations. |
| Age at menarche | The age at which a female experiences her first menstrual period. |
| Emergent infectious disease | A newly identified infectious disease that has recently evolved. |
| Reemergent infectious disease | Infectious disease that had previously been reduced but that increases in frequency when microorganisms evolve resistance to antibiotics. |
| Demography transition theory | A model of demographic shcang ethat states that as a poplation becomes economically developed, a reduction in death rates(leading to population growth) will take place, followed by a reduction in birth rates. |
| Age-sex structure | The number of males and females in different age groups of a population. |
| Population pyramid | A diagram of the age-sex structure of a population. |
