6-7 mya; found in Chad; oldest known (near-) hominid species350 cc brian size, suggested common ancestor of humans and chimps
6 mya; Kenya; fragmentary fossils; possible ancestor of Australopithecineslimbs 1.5x larger than Lucy, size of female chimp
5.2-5.8 mya; possibly forest-dwelling; most remains are skull fragmentsteeth remains somewhere between A. afarensis and earlier apes
4.2-3.9 mya; primitive skull/advanced body; tibia suggests bipedalityskull and body fragments assumed from same species, not confirmed
3.9-3.0 mya; skull similar to chimp; pelvis/legs/hands resemble modern humans375-550 cc, sexually dimorphic, either still partially adapted to living in trees or evolutionary baggage
3-2 mya; Lucy; bipedal; teeth very similar to human420-500 cc, reduced canines, slightly greater body size compared to afarensis
2.5 mya; known from partial skull; lumpers place it with afarensis 450 cc, big prognathism, perhaps tool users
2.6-2.3 mya; known for the black skull; mixture of primitive and advanced features410 cc, largest sagittal crest of any hominid
2-1.5 mya; body similar to africanus, more robust skull and teeth w/ flat face530 cc, huge molars for lots of chewing, possible digging tools
When and WhereSpeciesExtra Hints
2.1-1.1 mya; similar to robustus, face and teeth more massivecould be same species as robustus
2.4-1.5 mya; 'handy man;' similar brain shape to humans650 cc, possible capability of rudimentary speech
1.8 mya; Georgia; 3 partial skulls/jaws600-780 cc, intermediate between habilis and erectus
1.8 m - 300,000 ya; more robust skeleton than modern humans; Africa, Asia, Europe; Turkana boy750-1225 cc, probably used fire, stone tools more advanced than habilis
splitters-->African erectus species
500,000-200,000 ya; features between erectus and modern humans (brain size, skull shape, skeletal morphology)average 1200 cc
230,000-30,000 ya; bulkier than modern humans; prognathism; lived in cold climates, skeletons endured brutally hard liveshunters, buried their dead, Europe and Middle East, minor anatomical differences from humans (shoulder blade, pubic bone)
discovered on Indonesian island Flores; fully bipedal; used stone tools and firethought to be a dwarf form of erectus
