Assessing quantitative methods in archaeology via simulated datasets
Compared to what is found in many other scientific disciplines, archaeological data are typically scarce, biased and fragmented. This, coupled with the fact that archaeologists can rarely test their hypotheses using experimental design, makes archaeological inference and our ability to assess the robustness of quantitative methods used to make such inferences challenging. Archaeoriddle is a project that was born as an attempt to compare archaeolo…
Aridity, availability of drinking water and freshwater foods, and hominin and archeological sites during the Late Pliocene–Early Pleistocene in the western region of the Turkana Basin (Kenya)
A 4.3-million-year-old Australopithecus anamensis mandible from Ileret, East Turkana, Kenya, and its paleoenvironmental context
Lomekwi 3, West Turkana, Kenya
Modern human incursion into Neanderthal territories 54,000 years ago at Mandrin, France
Determining the extent of overlap between modern humans and other hominins in Eurasia, such as Neanderthals and Denisovans, is fundamental to understanding the nature of their interactions and what led to the disappearance of archaic hominins. Apart from a possible sporadic pulse recorded in Greece during the Middle Pleistocene, the first settlements of modern humans in Europe have been constrained to ~45,000 to 43,000 years ago. Here, we report …
Rethinking Orgnac 3 in Time and Space
An important aim in paleoanthropological and archaeological research is to clarify the poorly resolved record of the Middle Pleistocene (MP). Filling in the gaps of the Eurasian MP furthers our understanding of the behavioral and biological evolution of archaic humans, Neanderthals, Denisovans and their ancestors. Orgnac 3, located in Mediterranean France, is particularly suited to address these issues. This paper introduces the site to new reade…

Human burials at the Kisese II rockshelter, Tanzania
OBJECTIVES: The Late Pleistocene and early Holocene in eastern Africa are associated with complex evolutionary and demographic processes that contributed to the population variability observed in the region today. However, there are relatively few human skeletal remains from this time period. Here we describe six individuals from the Kisese II rockshelter in Tanzania that were excavated in 1956, present a radiocarbon date for one of the individua…
Analyse de sensibilité à des changements morphologiques du complexe de l'épaule
Si la fabrication et l’utilisation d’outils lithiques ont incontestablement joué un rôle déterminant dans l’évolution des hominines, l’impact de tels comportements sur leur morphologie semble moins faire consensus. Toutefois, il semble que l’architecture et les proportions du complexe de l’épaule chez les premiers représentants du genre Homo aient pu avoir été contraintes par ces comportements. Afin de discuter des potentiels avantages adaptatifs…
Lake-level changes and hominin occupations in the arid Turkana basin during volcanic closure of the Omo River outflows to the Indian Ocean
In the East African Rift, the western margin of Lake Turkana (northern Kenya) exposes Mio-Plio-Pleistocene lake sediments with dated volcanic horizons constraining basin dynamics at the astronomical time scale. Since the late Pliocene, coastal archaeological sites have formed within the lacustrine dynamics. Here, lake levels are reconstructed from 2.4 to 1.7 Ma using sedimentary facies and water/depth-controlled sediment association. The lacustri…

New archaeological investigations at the Lothagam harpoon site at Lake Turkana
The Lothagam harpoon site in north-west Kenya's Lake Turkana Basin provides a stratified Holocene sequence capturing changes in African fisher-hunter-gatherer strategies through a series of subtle and dramatic climate shifts (Figure 1). The site rose to archaeological prominence following Robbins's 1965-1966 excavations, which yielded sizeable lithic and ceramic assemblages and one of the largest collections of Early Holocene human remains from E…
An earlier origin for stone tool making
The discovery of the earliest known stone tools at Lomekwi 3 (LOM3) from West Turkana, Kenya, dated to 3.3 Ma, raises new questions about the mode and tempo of key adaptations in the hominin lineage. The LOM3 tools date to before the earliest known fossils attributed to Homo at 2.8 Ma. They were made and deposited in a more C 3 environment than were the earliest Oldowan tools at 2.6 Ma. Their discovery leads to renewed investigation on the timing…
Major Transitions in Human Evolution
Time travelers, flying heads, and second lives
Community + Culture features practitioner perspectives on designing technologies for and with communities. We highlight compelling projects and provocative points of view that speak to both community technology practice and the interaction design field as a whole. Tad Hirsch, Editor
Le Grand Abri aux Puces, a Mousterian site from the Last Interglacial
New views on old stones
Identifying sword marks on bone
Validation of plaster endocast morphology through 3D CT image analysis
A crucial component of research on brain evolution has been the comparison of fossil endocranial surfaces with modern human and primate endocrania. The latter have generally been obtained by creating endocasts out of rubber latex shells filled with plaster. The extent to which the method of production introduces errors in endocast replicas is unknown. We demonstrate a powerful method of comparing complex shapes in 3‐dimensions (3D) that is broadl…
