First fossil member of taxon: homo habilis, which means handy man . Researchers suggest that h. habilis is junk taxon and that there may be two more species of homo by 2. 0 mya. From sites in tanzania, kenya, and ethiopia (2. 3 - 1. 6 mya) Species designation: brain size and association with stone tools. May represent 2 or more different species (h. rudolfensis & h. habilis) First species in genus homo found outside africa (asia and south asia) Brain and body size changes in lineage. Early african specimens may be different species, homo ergaster. Distinguished from h. erectus by its thinner skull-bones and lack of an obvious supraorbital foramen. Debate on h. erectus or h. ergaster as direct ancestor of modern humans. Don"t know what it looks like post puberty. Europe and middle east (300 - 35 kya) Limb bones heavily marked by muscular attachments; thick walls of cortical bones & large joints.
