 It was once thought that "Australopithecus" could not produce tools like "Homo", but the discovery of "A. garhi" associated with large mammal bones bearing evidence of processing by stone tools showed this to not have been the case.Discovered in 1994, this was the oldest evidence of manufacturing at the time until the 2010 discovery of cut marks dating to 3.4 mya attributed to "A. afarensis", and the 2015 discovery of the Lomekwi culture from Lake Turkana dating to 3.3 mya possibly attributed to "Kenyanthropus".More stone tools dating to about 2.6 mya in Ledi-Geraru in the Afar Region were found in 2019, though these may be attributed to "Homo".
