The integration of fossils, phylogeny, and geochronology has resulted in an increasingly
well-resolved timetable of evolution. Life appears to have taken root before the earliest …

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 …

The possibility of a causal relationship between Earth history processes and hominin
evolution in Africa has been the subject of intensive paleoanthropological research for the …

The Acheulean is the longest-lasting human cultural record, spanning approximately 1.5 Ma
and three continents. The most comprehensive sequences are found in East Africa, where …

Reconstructing vegetation at hominin fossil sites provides us critical information about
hominin palaeoenvironments and the potential role of climate in their evolution. Here we …

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 …

Lakes act as major archives for continental paleoenvironments, particularly when the
evolution of lake levels over time serves as a guide for understanding regional …

The relatively continuous record of sedimentary deposits in the Koobi Fora Formation
preserve fossilized hominins and archaeological assemblages that are crucial in our …

Climate is thought to play a critical role in human evolution; however, this hypothesis is
difficult to test due to a lack of long, high-quality paleoclimate records from key hominin fossil …

A magnetostratigraphy for∼ 60 m of Koobi Fora Formation sediment in Area 104 was
derived from 46 oriented samples that produced well-resolved characteristic magnetizations …
