World Archaeology Test Two 1 *Humans and Neanderthals share the Fox P2 gene. It has to do with language. Mitochondrial DNA comes from the mom (100s to 1000s of copies in each cell). No contribution to humans is shown from examining mitochondrial DNA. The Upper Paleolithic Outline Origins of modern humans The spread of modern humans in the old world Upper Paleolithic culture and technology Origins of art What is a modern human? The term ‘modern human’ refers to all members of the subspecies Homo sapiens sapiens this includes all living humans. Modern human traits include: Globular braincase Reduced brow ridges Reduced body mass Unique pelvic shape Vertical forehead Pronounced chin Narrow trunk Reduced tooth size 1868 in Southern France Cro-Magnon man found. It was the first of the Homo sapien fossils. Origins and spread of modern humans Multi regional model- evolutions from H. erectus in several places Recent Out-of-Africa model- H. sapiens sapiens developed in Africa 200-100 kya radiated to other continents. Multi-Regional Model Gene flow between geographically separated populations prevented speciation. All living humans derive from the species Homo erectus that left Africa. Natural selection in regional populations responsible for regional variants (races). Says humans were in all different places and all evolved into the exact same thing. Unlikely.

World Archaeology Test Two 2 Emergence of Homo sapiens not restricted to any one area. This model is not very likey. Out of Africa Model After Homo erectus migration out of Africa different populations became reproductively isolated. Homo sapiens ultimately migrated out of Africa and replaced all other human populations without interbreeding. Modern human variation is a realatively recent phenomenon. Backed by research in mitochondrial DNA. Homo sapien sapien- first appearance in Africa 200,000 BP Europe 40,000 BP Asia 90,000 BP Australia 40,000 BP Homo sapien sapiens were the first species to live on every livable continent (this excludes Antartica) Recent Out-of-Africa Supported by molecular DNA evidence Supported by archaeological evidence Herto site, Ethiopia Modern humans at 160 kya Klasies River Mouth Caves, South Africa Genetic evidence supporting recent out of Africa model Living humans are very much homogeneous genetically Homogenetic contrasts with our living relatives (chimps) Highest degree of variation found in Africa populations ( because more time spent there to change) Small founding populations in Africa 400-100 kya Recent Out-of-Africa Evidence Difference between the archaeology records of modern humans in Africa and Neanderthals in Europe include: Variability in stone tools of Africa
