Overview

What is he best known for?

The fields of study he is best known for:

  • Archaeology
  • Paleontology
  • Ecology

His main research concerns Cave, Lower Paleolithic, Archaeology, Paleontology and Pleistocene. When carried out as part of a general Cave research project, his work on Speleothem is frequently linked to work in Hominidae, therefore connecting diverse disciplines of study. His Lower Paleolithic study combines topics from a wide range of disciplines, such as Blade, Upper Paleolithic, Middle Paleolithic and Zooarchaeology.

His Archaeology study combines topics in areas such as Paleozoology and Deciduous teeth. The study incorporates disciplines such as Mousterian and Southern Levant in addition to Paleontology. As a member of one scientific family, Ran Barkai mostly works in the field of Pleistocene, focusing on Lithic technology and, on occasion, Cenozoic and Quaternary.

His most cited work include:

  • Evidence for habitual use of fire at the end of the Lower Paleolithic: site-formation processes at Qesem Cave, Israel. (196 citations)
  • Cooperative hunting and meat sharing 400–200 kya at Qesem Cave, Israel (164 citations)
  • Evidence for the repeated use of a central hearth at Middle Pleistocene (300 ky ago) Qesem Cave, Israel (118 citations)

What are the main themes of his work throughout his whole career to date?

Ran Barkai mainly investigates Archaeology, Cave, Pleistocene, Lower Paleolithic and Paleontology. His work on Assemblage, Prehistory and Southern Levant as part of general Archaeology research is frequently linked to Scraper site and Context, bridging the gap between disciplines. His studies in Cave integrate themes in fields like Blade, Taphonomy and Hearth.

His study in Pleistocene is interdisciplinary in nature, drawing from both Stone tool, Human evolution, Neanderthal and Mammoth. His Lower Paleolithic study combines topics in areas such as Period, Lithic technology, Flake and Old World. His work focuses on many connections between Ecology and other disciplines, such as Upper Paleolithic, that overlap with his field of interest in Zooarchaeology.

He most often published in these fields:

  • Archaeology (69.67%)
  • Cave (57.38%)
  • Pleistocene (38.52%)

What were the highlights of his more recent work (between 2018-2021)?

  • Lower Paleolithic (31.15%)
  • Cave (57.38%)
  • Archaeology (69.67%)

In recent papers he was focusing on the following fields of study:

His primary areas of study are Lower Paleolithic, Cave, Archaeology, Pleistocene and Ecology. The various areas that he examines in his Lower Paleolithic study include Animal bone, Middle Paleolithic, Old World and Mineralogy. Ran Barkai has included themes like Sturnus, Corvus ruficollis and Early Pleistocene in his Middle Paleolithic study.

His studies deal with areas such as Type, Period and Hearth as well as Cave. His study in the field of Paleoanthropology, Acheulean and Prehistory also crosses realms of Functional role. His Pleistocene study integrates concerns from other disciplines, such as Zoology and Anatomy.

Between 2018 and 2021, his most popular works were:

  • Recycling for a purpose in the late Lower Paleolithic Levant: Use-wear and residue analyses of small sharp flint items indicate a planned and integrated subsistence behavior at Qesem Cave (Israel). (22 citations)
  • Animal residues found on tiny Lower Paleolithic tools reveal their use in butchery. (18 citations)
  • Are there marrow cavities in Pleistocene elephant limb bones, and was marrow available to early humans? New CT scan results from the site of Castel di Guido (Italy) (14 citations)

In his most recent research, the most cited papers focused on:

  • Archaeology
  • Ecology
  • Paleontology

Ran Barkai mainly focuses on Pleistocene, Lower Paleolithic, Cave, Archaeology and Flake. His Pleistocene research includes themes of Anatomy and Limb bones. His research integrates issues of Ecology, Old World, Corvus ruficollis and Archaeological record in his study of Lower Paleolithic.

He interconnects Zoology, Sturnus and Early Pleistocene in the investigation of issues within Cave. His work in the fields of Subsistence agriculture and Paleoanthropology overlaps with other areas such as Animal material, Process and Caloric intake. Ran Barkai integrates Flake with Survival strategy in his research.
