The appearance of Oldowan sites ca. 2.6 million years ago (Ma) may reflect one of the most
important adaptive shifts in human evolution. Stone artifact manufacture, large mammal …

This paper focuses on the empirical evidence for the cognitive abilities of early hominins of
the Oldowan Industrial Complex (c.≥ 2.6 to 1.4 Mya) on the African continent. It profiles …

The oldest Oldowan tool sites, from around 2.6 million years ago, have previously been
confined to Ethiopia's Afar Triangle. We describe sites at Nyayanga, Kenya, dated to 3.032 …

Relatively few remains of Late Pliocene hominids' knapping activities have been recovered
to date, and these have seldom been studied in terms of manual dexterity and technical …

East Africa has provided the earliest known evidence for Oldowan stone artifacts and
hominin-induced stone tool cutmarks dated to~ 2.6 million years (Ma) ago. The~ 1.8-million …

The emergence of lithic technology by∼ 2.6 million years ago (Ma) is often interpreted as a
correlate of increasingly recurrent hominin acquisition and consumption of animal remains …

Newly recorded archaeological sites at Gona (Afar, Ethiopia) preserve both stone tools and
faunal remains. These sites have also yielded the largest sample of cutmarked bones known …

Chimpanzees from the Taı̈ forest of Côte d'Ivoire produce unintentional flaked stone
assemblages at nut-cracking sites, leaving behind a record of tool use and plant …

Aridification is often considered a major driver of long-term ecological change and hominin
evolution in eastern Africa during the Plio-Pleistocene; however, this hypothesis remains …

Evidence of Oldowan tools by∼ 2.6 million years ago (Ma) may signal a major adaptive shift
in hominin evolution. While tool-dependent butchery of large mammals was important by at …
