The Great Rift Valley of Africa provides critical evidence for the evolution of early hominins.The earliest tools in the world can be found there as well: An unidentified hominin, possibly Australopithecus afarensis or Kenyanthropus platyops, created stone tools dating to 3.3 million years ago at Lomekwi in the Turkana Basin, eastern Africa.
Cleavers, found in many Acheulean assemblages such as Africa, were similar in size and manner of hand axes. The differences between a hand axe and a cleaver is that a hand axe has a more pointed tip, while a cleaver will have a more transverse "bit" that consists of an untrimmed portion of the edge oriented perpendicular to the long axis of the tool.
The brain anatomy of all Homo features an expanded cerebrum in comparison to australopithecines. The pattern of striations on the teeth of OH 65 slant right, which may have been accidentally self-inflicted when the individual was pulling a piece of meat with its teeth and the left hand while trying to cut it with a stone tool using the right hand.
Cro-Magnons were anatomically similar to present-day Europeans, West Asians, and North Africans; however, they were more robust, having larger brains, broader faces, more prominent brow ridges, and bigger teeth, compared to the present-day average. The earliest Cro-Magnon specimens also exhibit some features that are reminiscent of those found ...
Homo ergaster is an extinct species or subspecies of archaic humans who lived in Africa in the Early Pleistocene.Whether H. ergaster constitutes a species of its own or should be subsumed into H. erectus is an ongoing and unresolved dispute within palaeoanthropology.
Functional magnetic resonance imaging (fMRI) measures the brain activity through measuring the blood oxygen level in the brain. This test gives insight into which regions of the brain are active during a certain event. Event-related potentials (ERPs) measure the brain's activity through measuring electrical impulses by electrodes on the head ...

Tools made from bone, wood, or other organic materials were therefore in all probability used before the Oldowan. [15] Oldowan stone tools are simply the oldest recognisable tools which have been preserved in the archaeological record. [16] There is a flourishing of Oldowan tools in eastern Africa, spreading to southern Africa, between 2.4 and ...
