Around ___,000 years ago, archaic humans were using wood spears 2 meters long and hunting large game in an organized fashion
Which model of the origin of modern human evolution proposes that modern humans are the result of a speciation event in the late Pleistocene in Africa?
the Recent African Origin (RAO) model
Which model of the origin of modern human evolution proposes that modern humans are the most recent morphological form in a species, Homo sapiens, that has been around for nearly 2 million years?
the Multiregional Evolution model (MRE)
mtDNA studies, first released in 1987, reported that all modern human mtDNA can be traced to a population in _____ that lived approximately 150,000 to 200,000 years ago
Which model of the origin of modern human evolution has been dubbed the "Out of Africa, Again and Again" model?
The Multiple Dispersal model (MD)
The ____ model of human evolution predicts a strong, repeated impact by African populations on the genetic characteristics of humans over the last 1.7 my and also predicts recurrent gene flow between populations, with those closer to each other geographically sharing more genes than those more distant?
