Large brained babies: led to changes in the mechanics of bipedalism. Homo rudolfensis (2. 5-1. 8 mya: malawi but issues with the dating, anatomy. Robust jaw and teeth but less than australopiths. Deep mandibles: no post cranial material. First stone tools date ( 2. 5 mya) similar to in time to appearance of homo habilis.
