Background Until recently, the evolution of the genus Homo has been interpreted in the
context of the onset of African aridity and the expansion of open grasslands. Homo erectus …

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 …

The role of African savannahs in the evolution of early hominins has been debated for nearly
a century. Resolution of this issue has been hindered by difficulty in quantifying the fraction …

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 …

The habitual consumption of large-animal resources (eg, similar sized or larger than the
consumer) separates human and nonhuman primate behavior. Flaked stone tool use …

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 …

Evaluating the relationships between climate, the environment, and human traits is a key
part of human origins research because changes in Earth's atmosphere, oceans …

It has long been proposed that pre-modern hominin impacts drove extinctions and shaped
the evolutionary history of Africa's exceptionally diverse large mammal communities, but this …
