Document Summary

Ardipithecus (5. 8-4. 4 mya) (new genus begins) australopithecus anamensis (4. 2-3. 9 mya) australopithecus afarensis (3. 8-3 mya) a africanus (3-2 mya) & a. boisei (2. 6-1. 2 mya) a. robustus (2-1 mya) & a. garhi (2. 5 mya) The crest is needed for muscle attachment to cheek bones. Homo habilis (handyman) 2. 4-1. 4 million years ago , only found in africa. Big leap from homo habilis to homo erectus (1 mya - 300000 years ago) in africa, Asia, and europe archaic h. sapiens (300000-28000 years ago) anatomically modern humans (150000 years ago to now) worldwide release. Neandertal mystery (130000-28000 years ago) in europe and sw asia. Out of africa : based on mtdna, single species from africa, replaced other living hominins. Multi-regional hypothesis : gradual evolution linked by complex gene flow. Behavioral modernity is associated with symbolic thought (language, art, religion, complex tools, humor, ) Central focus of the debate: svante paabo"s mapping of the neandertal genome.
