Document Summary
Morphological transitions through time during hominin evolution. Most large mammalian carnivores practice hunting and scavenging (such as cheetahs) Hominins might have stolen kills from carnivores. Hunting tooth marks on top of cut marks. Scavenging cut marks on top of carnivore tooth marks. First use of stone preceded the first stone tools that were modified by humans. This could have included a transition stage where rocks were first shattered before use. First stone tools that were clearly modified date to around 2 mya. Earliest tools found in a river in ethiopia. Other tools have been found around this time in tanzania, kenya and south africa. Unknown which hominin was responsible, but could be a. garhi, h. habilis, h. ergaster. This mode 1 technology overlapped in time with the next technology, maybe because of variation among or within species. Hammer stones used to bang a core stone to obtain flakes from the core.
