Using information from primatology, functional morphology, phylogeny, archeology, and paleoanthropology, we argue that before 2.5 mya hominins may have used tools, including unmodified and possibly modified stone tools (Fig. 1). We consider several scenarios to explain why stone tool manufacture and use might not have left archeological traces prior to 2.5 mya and conclude by suggesting means to test our hypotheses. 
ARCHAEOLOGICAL RECORDS | 2.7 MYR-300,000 years ago in Africa
The archeological record of the African continent preserves the longest record of human behavior anywhere in the world. This article discusses behavioral evolution from the Oldowan through the
The Oldowan: The Tool Making of Early Hominins and Chimpanzees Compared
The Oldowan was the term first coined by Louis Leakey to describe the world's earliest stone industries, named after the famous site of Olduvai (formerly Oldoway) Gorge in Tanzania. The Oldowan
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 Primitive Wrist of Homo floresiensis and Its Implications for Hominin Evolution
Analysis of wrist bones from the holotype specimen (LB1) shows that it retains wrist morphology that is primitive for the African ape-human clade, indicating that LB1 is not a modern human with an undiagnosed pathology or growth defect; rather, it represents a species descended from a hominin ancestor that branched off before the origin of the clade that includes modern humans, Neandertals, and their last common ancestor.
From Nothing to Something: The Appearance and Context of the Earliest Archaeological Record
Before 2.6 million years ago (Ma), no archaeological record has been securely documented, and therefore there is no evidence of hominin tool use. Then, at 2.6–2.58 Ma, there is widespread evidence

Towards a prehistory of primates
Using the behaviour of related primates to provide analogies for early humans has a long tradition in archaeology. But these primates too have a past, and experienced particular contexts for the
Grammatical equivalents of Palaeolithic tools: a hypothesis
The hypothesis is that grammatical equivalents inherent to stone tool work guide the evolution of language.

Abstract Some of the more important evidence is reviewed for the archaeology of hominin colonization associated with the Early-Middle Pleistocene transition. This is done by reference to the nature
From Homogeneity to Multiplicity: A New Approach to the Study of ArchaicStone Tools
Evidence from sites both in Africa and in Eurasia points towards an ever expanding archaeological record for archaic industries attributed largely to the Oldowan tradition. We have therefore found it


Fossil evidence for early hominid tool use.
A test for humanlike precision grasping (the enhanced ability to manipulate tools) is proposed and applied to australopithecines and early Homo and indicates that tools were likely to have been used by all early hominids at around 2.0 million years ago.

This analysis suggests that modified bones from the Lower Paleolithic sites of Swartkrans and Sterkfontein in South Africa were used to dig into termite mounds, rather than to dig for tubers, which indicates that early hominids from southern Africa maintained a behavioral pattern involving a bone tool material culture that may have persisted for a long period and strongly supports the role of insectivory in theEarly hominid diet.
Hand of Paranthropus robustus from Member 1, Swartkrans: fossil evidence for tool behavior.
Functional morphology suggests that Paranthropus could have used tools, possibly for plant procurement and processing, and the new fossils suggest that absence of tool behavior was not responsible for the demise of the "robust" lineage.
Paleolithic Technology and Human Evolution
This work has shown that stone tool technology, robust australopithecines, and the genus Homo appeared almost simultaneously 2.5 million years ago, and once this adaptive threshold was crossed, technological evolution was accompanied by increased brain size, population size, and geographical range.
Environment and behavior of 2.5-million-year-old Bouri hominids.
The combined evidence suggests that behavioral changes associated with lithic technology and enhanced carnivory may have been coincident with the emergence of the Homo clade from Australopithecus afarensis in eastern Africa.
The origin of man.
Evidence provided by the fossil record, primate behavior, and demographic analysis shows that the traditional view that early human evolution was a direct consequence of brain expansion and material culture is incorrect, and that the unique sexual and reproductive behavior of man may be the sine qua non of human origin.
Early hominid brain evolution: a new look at old endocasts.
The brain morphology of Australopithecus africanus appears more human like than that of Paranthropus in terms of overall frontal and temporal lobe shape, and new data do not support the proposal that increased encephalization is a shared feature between Par anthropus and early Homo.
Excavation of a Chimpanzee Stone Tool Site in the African Rainforest
The data unearthed show that chimpanzees transported stones from outcrops and soils to focal points, where they used them as hammers to process foodstuff and the repeated use of activity areas led to refuse accumulation and site formation.
A new hominid from the Upper Miocene of Chad, Central Africa
The discovery of six hominid specimens from Chad, central Africa, 2,500 km from the East African Rift Valley, suggest that the earliest members of the hominids clade were more widely distributed than has been thought, and that the divergence between the human and chimpanzee lineages was earlier than indicated by most molecular studies.

As the oldest known lithic technology (ca. 2.5-1.5 my B.P.), the Oldowan exhibits the simplest methods of stone tool flaking and utilization. Certain Oldowan artifact assemblages (<2.0 my B.P.) also
