The Acheulian is one of the first defined prehistoric techno-complexes and is characterized by shaped bifacial stone tools. It probably originated in Africa, spreading to Europe and Asia perhaps as early as ∼1 million years (Myr) ago. The origin of the Acheulian is thought to have closely coincided with major changes in human brain evolution, allowing for further technological developments. Nonetheless, the emergence of the Acheulian remains unclear because well-dated sites older than 1.4 Myr… Expand
The Origin of The Acheulean: The 1.7 Million-Year-Old Site of FLK West, Olduvai Gorge (Tanzania)
TLDR
A detailed technological study is provided and evidence of the use of these tools on the butchery and consumption of fauna, probably by early Homo erectus sensu lato is provided, showing that complex cognition was present from the earliest stages of the Acheulean. Expand
The characteristics and chronology of the earliest Acheulean at Konso, Ethiopia
TLDR
A newly established chronometric calibration is provided for the Acheulean assemblages of the Konso Formation, southern Ethiopia, which span the time period ∼1.75 to <1.0 Ma, paralleling the emergence of Homo erectus-like hominid morphology. Expand
The Origins of the Acheulean at Olduvai Gorge (Tanzania): A New Paleoanthropological Project in East Africa
The disappearance of the earliest human culture, the Oldowan, and its substitution by a new technology, the Acheulean, is one of the main topics in modern Paleoanthropology. Recent research hasExpand
The Early Acheulian of north-western Europe
Abstract The introduction of biface technology in the Lower Palaeolithic arguably marked a fundamental change in how early hominins dealt with their world. It is suggested to reflect changes not justExpand
Early Pleistocene occurrence of Acheulian technology in North China
Acheulian tools with their associated level of cognizance heralded a major threshold in the evolution of hominin technology, culture and behavior. Thus, unraveling occurrence ages of AcheulianExpand
The expansion of later Acheulean hominins into the Arabian Peninsula
TLDR
Findings reveal a climatically-mediated later Acheulean expansion into a poorly known region, amplifying the documented diversity of Middle Pleistocene hominin behaviour across the Old World and elaborating the terminal archaic landscape encountered by the authors' species as they dispersed out of Africa.

The Transition to the Acheulean in East Africa: an Assessment of Paradigms and Evidence from Olduvai Gorge (Tanzania)
The origin of the Acheulean constitutes a key aspect of current research in the archaeology of human evolution. Olduvai Gorge is one of the main sites in Africa in the study of the transition fromExpand

The Acheulean Assemblages of Asia: A Review
Acheulean assemblages—defined by the presence of handaxes and cleavers—are found across much of Asia. The best known are from the Levant and India and date from the Early Pleistocene. AlthoughExpand

Early Pleistocene Presence of Acheulian Hominins in South India
TLDR
New ages from the excavated site of Attirampakkam reveal that, during the Early Pleistocene, India was already occupied by hominins fully conversant with an Acheulian technology including handaxes and cleavers among other artifacts, implying that a spread of bifacial technologies across Asia occurred earlier than previously accepted.

Age of the earliest known hominids in Java, Indonesia.
TLDR
The hominid fossils, a juvenile calvaria of Pithecanthropus and a partial face and cranial fragments of Meganthropus, commonly considered part of the Asian Homo erectus hypodigm, are at least 0.6 million years older than fossils referred to as Homo erectu from Olduvai Gorge, Tanzania, and comparable in age with the oldest Koobi Fora Homo cf.

Implications of new early Homo fossils from Ileret, east of Lake Turkana, Kenya
TLDR
Two new cranial fossils from the Koobi Fora Formation, east of Lake Turkana in Kenya, are described that have bearing on the relationship between species of early Homo and confirm the distinctiveness of H.’shabilis and H.erectus, independently of overall cranial size, and suggest that these two early taxa were living broadly sympatrically in the same lake basin for almost half a million years.

The oldest hand-axes in Europe
TLDR
Palaeomagnetic analysis of two western Mediterranean hand-axe sites found reverse polarity magnetozones, showing that hand-axes were already in Europe as early as 0.9 Myr ago, which supports a wide geographic distribution of Palaeolithic bifacial technology outside of Africa during the Early Pleistocene.
