Document Summary
Archaic forms of modern humans first appeared ca. 350kya: development of modern humans took place at different times in different places. First modern humans appeared in africa around 160,000 years ago and later in europe. These populations dispersed from africa to most other parts of the world by at least 40,000 years ago. These modern humans replaced pre-existing archaic populations: ex. 3 hypotheses for modern human origins: complete replacement (out of africa, amhs (anatomically modern homo sapiens) arose in africa ca. 200kya migrated and replaced all archaic homo living in europe and asia: speciation event, no biological mixture with european forms (eg. neanderthals) because africa amhs were new species, supported by dna evidence. Africans have greater genetic diversity than anywhere else. Mtdna (mitochondrial dna passed down from mother) from 8 neanderthals (1997-2004) Neanderthals and newly migrating homo sapiens from africa: neanderthals contribute genes to european and european-descended populations. Supported by dna evidence: sequencing of neanderthal genome.
