Human biological and cultural evolution are closely
linked to technological innovations. Direct evidence for tool
manufactureand use is absent before 2.5 million years ago (Ma), so
reconstructionsof australopithecine technology are based mainly on the
behaviorand anatomy of chimpanzees. Stone tool technology, robust
australopithecines,and the genus Homo appeared almost
simultaneously 2.5 Ma. Oncethis adaptive threshold was crossed,
technological evolution wasaccompanied by increased brain size,
population size, and geographicalrange. Aspects of behavior, economy,
mental capacities, neurologicalfunctions, the origin of grammatical
language, and social andsymbolic systems have been inferred from the
archaeological recordof Paleolithic technology.
