A. Africanus and A. robustus South Africa 3-2.5mya Africanus—gracile (slighter; less muscle; like a Bonobo) Robustus—robust (more muscular) Large back teeth; also a larger species 60% female dimorphic Evidence for scavenging or hunting; given the teeth and context of finds that have bones Robustus—sagittal crest: a piece of bone sticking out of the skull. A. Boisei Larger and more muscled than robustus; much more robust Molars are 3x size of human molars Slight increase in brain size Brain is only 1/3 the size of ours Philogenetic map: Several species of hominids in a relatively close area Contemporary species; multiple species of hominids existed simultaneously Chronology is more like a bush than a direct progression Avoidance and conflict: Law of competitive exclusion: With these contemporary species they had to be exploiting different niches . They cannot all be eating the same thing at the same time.
