Other branches of australopithecines: a. africanus hits extinction at 1mya, a. afarensis hits extinction at 1mya. Used tools: a. garhi hits extinction at 1mya. They began eating meat: homo habilis extinction around 2mya. Led to homo erectus: homo erectus extinction around 2mya. Brain size increased to 900ml: homo sapiens hit extinction around . 190mya. Led to h. s neanderthalensis: h. s neanderthalensis hit extinction around 0. 02mya. Anamensis afarensis garhi habils erectus sapeins.
