Human evolutionary scholars have long supposed that the earliest stone tools were made by the genus Homo and that this technological development was directly linked to climate change and the spread of savannah grasslands. [] Key Method The Lomekwi 3 knappers, with a developing understanding of stone’s fracture properties, combined core reduction with battering activities. Given the implications of the Lomekwi 3 assemblage for models aiming to converge environmental change, hominin evolution and technological…
Three thousand years of wild capuchin stone tool use
This work applies archaeological excavation, dating and analytical techniques to a wild capuchin monkey site in Serra da Capivara National Park, Brazil and presents the first example of long-term tool-use variation outside of the human lineage.
Earliest known Oldowan artifacts at >2.58 Ma from Ledi-Geraru, Ethiopia, highlight early technological diversity
A substantial assemblage of systematically flaked stone tools excavated in situ from a stratigraphically constrained context at LG bracketed between 2.61 and 2.58 Ma suggests that hominin technology is distinctly different from generalized tool use that may be a shared feature of much of the primate lineage.
Could woodworking have driven lithic tool selection?
Group-specific archaeological signatures of stone tool use in wild macaques
The results suggest that tool-use may develop differently within species of old-world monkeys, and that the evidence of material culture can differ within the same timeframe at local geographic scales and in spite of shared environmental and ecological settings.

This research indicates that hominin activities were situated in an open habitat within a grassland dominated ecosystem, the first documentation of an archaeological site in such an open setting, and suggest that the Kanjera hominins utilized a technological system that allowed them to extract nutrient dense animal and plant foods from their environment.
Oldowan stone knapping and percussive activities on a raw material reservoir deposit 1.4 million years ago at Barranco León (Orce, Spain)
Barranco León (Orce, Andalusia, Spain) provides the oldest case of knapping and percussive activities on an ancient raw material reservoir deposit. This site has already proven to be one of the


2.5-million-year-old stone tools from Gona, Ethiopia
The artefacts show surprisingly sophisticated control of stone fracture mechanics, equivalent to much younger Oldowan assemblages of Early Pleistocene age, which indicates an unexpectedly long period of technological stasis in the Oldowan.
Early hominid stone tool production and technical skill 2.34 Myr ago in West Turkana, Kenya
A technological analysis of the core reduction sequences is described, based on these refits, which allows unprecedented accuracy in the understanding of flake production processes and can demonstrate greater cognitive capacity and motor skill than previously assumed for early hominids.
The cutting edge : new approaches to the archaeology of human origins
This book focuses on innovative new approaches to the archaeological evidence for protohuman behavior found in the Early Stone Age, based on a recent international conference held at the Stone Age
Evidence for stone-tool-assisted consumption of animal tissues before 3.39 million years ago at Dikika, Ethiopia
The discovery of stone-tool-inflicted marks on bones found during recent survey work in Dikika, Ethiopia, extends by approximately 800,000 years the antiquity of stone tools and ofStone- tool-assisted consumption of ungulates by hominins and can now be attributed to Australopithecus afarensis.
Paleoenvironments of the earliest stone toolmakers, Gona, Ethiopia
Fluvio-lacustrine sediments of the Hadar and Busidima Formations along the northern Awash River (Ethiopia) archive almost three million years (3.4 to <0.6 Ma) of human evolution, including the
4,300-Year-old chimpanzee sites and the origins of percussive stone technology
The “Chimpanzee Stone Age” pre-dates the advent of settled farming villages in this part of the African rainforest and suggests that percussive material culture could have been inherited from an common human–chimpanzees clade, rather than invented by hominins.

The history of research on the origins of stone knapping in Africa and the current evidence in a historical perspective is summarized and the first unmistakable evidence of tool-making dates to 2.6 Ma, the period in which Oldowan assemblages first appear in the East African record.
The origins of stone tool technology in Africa: a historical perspective
The search for the earliest stone tools is a topic that has received much attention in studies on the archaeology of human origins. New evidence could position the oldest traces of stone tool-use
