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 …

Climate variability and hominin evolution are inextricably linked. Yet, hypotheses examining
the impact of large-scale climate shifts on hominin landscape ecology are often constrained …

Our own species, Homo sapiens, has been able to invade near-all global ecosystems
through a unique form of ecological plasticity. To understand how Homo sapiens have been …

To investigate the role of vegetation and ecosystem diversity on hominin adaptation and
migration, we identify past human habitat preferences over time using a transient 3-million …

In celebration of the 50th anniversary of the Journal of Human Evolution, we re-evaluate the
fossil record for early Homo (principally Homo erectus, Homo habilis, and Homo rudolfensis) …

We developed a composite outcrop proxy record of Plio-Pleistocene climate in eastern
Africa using the radiometrically-dated sediments of the Omo Group that preserve evidence …

Plant wax biomarkers are an innovative proxy for reconstructing vegetation composition and
structure, rainfall intensity, temperature, and other climatic and environmental dynamics …

In evolutionary medicine and other related fields, the concept of evolutionary mismatch is
used to explain phenomena whereby traits reduce in adaptive value and eventually become …

Abstract The Homa Peninsula, in southwestern Kenya, continues to yield insights into
Oldowan hominin landscape behaviors. The Late Pliocene locality of Nyayanga (∼ 3–2.6 …

The Oldowan represents the earliest recurrent evidence of human material culture and one
of the longest-lasting forms of technology. Its appearance across the African continent amid …
