The Acheulean technological tradition, characterized by a large (>10 cm) flake-based component, represents a significant technological advance over the Oldowan. Although stone tool assemblages attributed to the Acheulean have been reported from as early as circa 1.6–1.75 Ma, the characteristics of these earliest occurrences and comparisons with later assemblages have not been reported in detail. Here, we provide a newly established chronometric calibration for the Acheulean assemblages of the Konso Formation, southern Ethiopia, which span the time period ∼1.75 to <1.0 Ma. The earliest Konso Acheulean is chronologically indistinguishable from the assemblage recently published as the world’s earliest with an age of ∼1.75 Ma at Kokiselei, west of Lake Turkana, Kenya. This Konso assemblage is characterized by a combination of large picks and crude bifaces/unifaces made predominantly on large flake blanks. An increase in the number of flake scars was observed within the Konso Formation handaxe assemblages through time, but this was less so with picks. The Konso evidence suggests that both picks and handaxes were essential components of the Acheulean from its initial stages and that the two probably differed in function. The temporal refinement seen, especially in the handaxe forms at Konso, implies enhanced function through time, perhaps in processing carcasses with long and stable cutting edges. The documentation of the earliest Acheulean at ∼1.75 Ma in both northern Kenya and southern Ethiopia suggests that behavioral novelties were being established in a regional scale at that time, paralleling the emergence of Homo erectus- like hominid morphology.

Modern humans replaced Neandertals ∼40,000 y ago. Close to the time of replacement, Neandertals show behaviors similar to those of the modern humans arriving into Europe, including the use of specialized bone tools, body ornaments, and small blades. It is highly debated whether these modern behaviors developed before or as a result of contact with modern humans. Here we report the identification of a type of specialized bone tool, lissoir , previously only associated with modern humans. The microwear preserved on one of these lissoir is consistent with the use of lissoir in modern times to obtain supple, lustrous, and more impermeable hides. These tools are from a Neandertal context proceeding the replacement period and are the oldest specialized bone tools in Europe. As such, they are either a demonstration of independent invention by Neandertals or an indication that modern humans started influencing European Neandertals much earlier than previously believed. Because these finds clearly predate the oldest known age for the use of similar objects in Europe by anatomically modern humans, they could also be evidence for cultural diffusion from Neandertals to modern humans.

South Asia is rich in Lower Paleolithic Acheulian sites. These have been attributed to the Middle Pleistocene on the basis of a small number of dates, with a few older but disputed age estimates. Here, we report new ages from the excavated site of Attirampakkam, where paleomagnetic measurements and direct ²⁶Al/¹⁰Be burial dating of stone artifacts now position the earliest Acheulian levels as no younger than 1.07 million years ago (Ma), with a pooled average age of 1.51 ± 0.07 Ma. These results 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. This implies that a spread of bifacial technologies across Asia occurred earlier than previously accepted.

Archaeological and palaeontological evidence from the Early Stone Age (ESA) documents parallel trends of brain expansion and technological elaboration in human evolution over a period of more than 2 Myr. However, the relationship between these defining trends remains controversial and poorly understood. Here, we present results from a positron emission tomography study of functional brain activation during experimental ESA (Oldowan and Acheulean) toolmaking by expert subjects. Together with a previous study of Oldowan toolmaking by novices, these results document increased demands for effective visuomotor coordination and hierarchical action organization in more advanced toolmaking. This includes an increased activation of ventral premotor and inferior parietal elements of the parietofrontal praxis circuits in both the hemispheres and of the right hemisphere homologue of Broca's area. The observed patterns of activation and of overlap with language circuits suggest that toolmaking and language share a basis in more general human capacities for complex, goal-directed action. The results are consistent with coevolutionary hypotheses linking the emergence of language, toolmaking, population-level functional lateralization and association cortex expansion in human evolution.

The Acheulian presence in the Dead Sea Rift and its environs is characterized by the discontinuity of its cultural manifestations. Nevertheless, the long stratigraphic sequences of the Acheulian Technocomplex provide a unique opportunity for synergetic examination along a temporal trajectory. Hominin cognitive and cultural behaviour are studied at Gesher Benot Yaʿaqov through analyses of lithic, palaeontological and palaeobotanical assemblages, as well as the Early–Middle Pleistocene environment, ecology and climate. The study attempts to reconstruct reduction sequences of some major artefact groups at the site, which include raw material acquisition, production, technology, typology, usage and discard. Experimental archaeology illustrates artefact mobility on the palaeo-landscape. Strategies of biomass-exploitation are studied in detail, with other aspects yielding additional information on hominin subsistence and adaptive responses to their environment. The cultural marker of fire and the spatial association of selected categories of finds are integrated in the general synthesis, allowing reconstruction of the cultural and cognitive realm of Acheulian hominins. The synthesis attempts to reassess the abilities, social structure, subsistence and adaptability to the changing environment of hominins in the Levantine Corridor.

This paper presents an overview of the Chinese Paleolithic industries between 300 ka and 40 ka, a time span now termed the “later Early Paleolithic” (LEP) in the Chinese chronological scheme. It describes the unique features of LEP remains in China compared with contemporaneous materials in Africa and western Eurasia as well as the internal diversity and complexity of these Chinese Paleolithic assemblages. Basic features of LEP remains in China include the persistent and conservative pebble-tool and simple flake-tool traditions, the use of poor-quality local raw materials, tool fabrication on pebbles and direct use of unretouched flakes, opportunistic flaking, simple and casual modification, and the lack of obvious temporal trends. The diversity and complexity of Chinese Paleolithic cultures as they are expressed in terms of the major difference between southern China’s pebble-tool tradition and northern China’s simple flake-tool tradition are also assessed. Based on such generalizations and analyses, a comprehensive behavioral model is proposed to explain the unique features of LEP cultures in China and the alternative pathway of human evolution and adaptation in China during that period of time.

The fields of Design and Archaeology keenly understand culture as viewed through a material and technological prism. At a time when data are viewed as a ‘new material’, one that can be stored, compressed, collected, and mined, digital tools are snapshots of our technological capabilities and cultural interests. The making of design for debate objects is a practice employed to raise questions and test the boundaries of what is expected of the material world around us. This article details a series of design works of knapped flint hand-axes that were 3D-scanned, processed, and worked in their malleable digital material state and reborn into the physical world using various contemporary fabrication technologies and materials. The pairing of a 3D-printed nylon object with its lithic-technology previous self allows for a glimpse at the journey traveled, both materially and technologically, and in terms of time and our species' evolution.

In recent years, the nature, significance, and validity of the British core-and-flake assemblage known as the Clactonian have come under close scrutiny. More traditional ideas, which see the Clactonian as the product of a distinct, non-handax-making technical tradition, are being challenged by notions of a single European knapping repertoire in which the proportion of handaxes varies according to factors such as activity facies, local raw material potential, and landscape use. Furthermore, recent technological studies which show a basic technological parity between the Acheulean and the Clactonian, including claims for rare atypical bifaces within the Clactonian, have been argued as eroding the very rationale for seeing the Clactonian as a separate entity. These challenges have gained widespread acceptance, despite a lack of empirical support in some cases, questionable conclusions, and hints of a widely ignored, yet intriguing chronological recurrence. A review of the empirical basis and interpretation of the Clactonian, in both recent years and the recent past, suggests that the Clactonian is in danger of being explained away, rather than explained.

The Acheulean, sometimes known as 'the great handaxe tradition', is the longest-lasting entity in the human cultural record. The oldest sites are in Africa at around 1.6 million years ago and the most recent approach the last 100,000 years. The geographical extent is also enormous, ranging across Africa, the Middle East, most of Europe and large parts of Asia. Is it however a real tradition? The Acheulean represents a set of stone-working ideas that endure, but the strength of 'tradition' is often an assumption made by archaeologists. This paper re-examines Acheulean biface variation, looking at sets of assemblages measured in different ways, but amenable to discriminant analysis (DFA), which is able to highlight differences useful in classification. The analyses show significant differences between European and African assemblages. In the case of the Far East, in line with others, we provide further analyses suggestive of technological differences between putative 'handaxes' from Korea and some 'classic' western assemblages. However, it is not yet fully clear how far a 'typical' Acheulean tradition is represented, as matching of Far Eastern assemblages to other parts of the world depends to an extent upon the criteria used. With regard to the more general Acheulean paradox, the paper notes parallels in biological studies with the idea that a single widely extending phenomenon can incorporate elements of both unity and diversity.

The ability to detach large (larger than 10 cm) flakes from giant cores and use them as blanks for the production of handaxes and cleavers is a technological hallmark distinguishing the Acheulian culture from its African predecessor, the Developed Oldowan, approximately 1.5 million years ago. Acheulian knappers applied a variety of fundamentally different, innovative, and sophisticated methods to large‐flake production that were perfectly suited to the size and shape of the naturally available raw materials. Yet the end products of all these methods were astonishingly similar across the geographical and chronological distribution of the Acheulian techno‐complex: large flakes that were suitable in size and morphology for the production of handaxes and cleavers.
