Term
anatomically modern humans
Definition
The modern form of the human species, which dates back 200,000 years.
Term
Homo floresiensis
Definition
The species name given to a very small hominin that lived in Indonesia in recent times, and thought to be a dwarf species of Homo erectus.
Term
Upper Paleolithic
Definition
A general term used to collectively refer to the stone tool technologies of anatomically modern Homo sapiens.
Term
Lower Paleolithic
Definition
A general term used to collectively refer to the stone tool technologies of Homo habilis/Homo rudolfensis and Homo erectus.
Term
Middle Paleolithic
Definition
A general term used to refer collectively to the stone tool technologies of H. heidelbergensis and Neandertals.
Term
blade
Definition
A stone tool characteristic of the Upper Paleolithic, defined as being at least twice as long as it is wide.
Term
burin
Definition
A stone tool with a sharp edge that is used to cut and engrave bone.
Term
multiregional evolution model
Definition
The hypothesis that modern humans evolved throughout the Old World as a single species after the first dispersion of Homo erectus out of Africa.
Term
most recent common ancestor (MRCA)
Definition
The most recent individual from which a set of organisms are descended.  MCRAs are estimated from genetic data and are different for different loci.
Term
African replacement model
Definition
The hypothesis that modern humans evolved as a new species in Africa 200,000 years ago and then spread throughout the Old World, replacing preexisting human populations.
Term
assimilation model
Definition
The hypothesis that modern human anatomy arose first in Africa as a change within a species and then spread through gene flow to populations outside of Africa.  The gene pool of the non-African populations was thus assimilated into an expanding population of modern humans out of Africa.
Term
regional continuity
Definition
The appearance of similar traits within a geographic region that remain over a long period of time.
