From sites in tanzania, kenya, ethiopia (2. 3 - 1. 6 mya) Species destination: brain size & association with stone tools. First species of homo or junk taxon. May represent 2 or more different species (h. rudolfensis & h. habilis) H. rudolfensis or h. habilis first representative of our genus. First species in genus homo found outside africa (asia & southeast asia) Brain & body size changes in lineage. Controlled the use of fire & hunting. Early african specimens may be different species, homo ergaster. Distinguished from h. erectus by its thinner skull bones & lack of an obvious supraorbital foramen. Debate on h. erectus or h. ergaster as direct ancestor of modern humans. Limb bones heavily marked by muscular attachments; thick walls of cortical bone & large joints.
