A unique hominin menu dated to 1.95 million years ago.
R esearch on ancient foragers has tended to focus on their acquisition of large land mammals, but our ancestors in fact exploited a wider range of taxa. Depending on the local environment, this range included tortoises, birds, and hares from terrestrial habitats and mollusks, birds, and fish from aquatic habitats. These small terrestrial animals and aquatic species begin to appear occasionally ...
متن کاملTwo Acheuleans, two humankinds: From 1.5 to 0.85 Ma at Melka Kunture (Upper Awash, Ethiopian highlands).
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, in largescale syntheses, the Lower Pleistocene Acheulean (LPA) has often been considered a uniform cultural entity. Furthermore, the emergence and development of Acheulean technology are seen as linked to the emergence ...
متن کاملThe Unknown Oldowan: ~1.7-Million-Year-Old Standardized Obsidian Small Tools from Garba IV, Melka Kunture, Ethiopia
The Oldowan Industrial Complex has long been thought to have been static, with limited internal variability, embracing techno-complexes essentially focused on small-to-medium flake production. The flakes were rarely modified by retouch to produce small tools, which do not show any standardized pattern. Usually, the manufacture of small standardized tools has been interpreted as a more complex b...
متن کامل0 The nuclear interaction at Oklo 2 billion years ago ∗
We re-examine the effort to constrain the time-variability of the coupling constants of the fundamental interactions by studying the anomalous isotopic abundance of Sm observed at the remnants of the natural reactors which were in operation at Oklo about 2 billion years ago, in terms of a possible deviation of the resonance energy from the value observed today. We rely on new samples that were ...
متن کاملThe Nuclear Interaction at Oklo 2 Billion Years Ago *
We re-examine Shlyakhter’s effort to constrain the time-variability of the coupling constants of the fundamental interactions by studying the anomalous isotopic abundance of Sm observed at the remnants of the natural reactors which were in operation at Oklo about 2 billion years ago. We rely on new samples that were carefully collected to minimize natural contamination and also on a careful tem...
