In this paper, we discuss human occupation during the Early and Middle Holocene in the Eastern Desert of Egypt, based mainly on the data provided by excavated deposits from the Sodmein Cave, which produced an important Holocene stratigraphic sequence. This sequence is dated by a large number of conventional and AMS 14C dates. It appears that the area was empty of human occupation during the Late Glacial Maximum (LGM) and the earliest Holocene. With improved climatic conditions, humans arrived in the area, as hunter-gatherers using no ceramics, from around 7.1 to 6.4 Ka cal BC. Humans were absent from the cave during the Holocene 8.2 Ka event (ca. 6.3 Ka cal BC). From 6.2 to 5.0 Ka cal BC, herders visited the site on a regular basis importing caprines. The bone evidence for domesticated small stock is very limited at Sodmein but is nevertheless extremely important, as it contains the oldest known specimens for Africa to date. After 5.0 Ka cal BC, the area was almost entirely deserted.

Bioarchaeological studies of human remains examine past populations through their mortuary, biological, and socio-cultural contexts. Biological distance, or biodistance, analyses use both genetic and phenetic data to investigate biological relatedness. Biodistance studies frequently employ phenotypic characteristics, or the physical expression of genetic traits that can serve as a proxy for aDNA, to understand evolution, migration, kinship and social organisation. We used phenotypic variation in dental morphology to investigate the population history of the Khabur basin in Syria, during an important period of urbanisation in the Early Bronze Age (EBA, circa 3000-2100 BCE) that shaped the political, social, and economic history of ancient Mesopotamia. Non-metric dental traits from three EBA sites, Tell Brak (n=77), Tell Barri (n=16) and Tell Arbid (n=17), were recorded using the Arizona State University Dental Anthropology System (ASUDAS). Individuals from the sites were compared using the Gower distance matrix and Mean Measure of Divergence (MMD) to examine the difference between sites as population groups. The results suggest that while sites were ancestrally similar, the observed heterogeneity between sites and was related to the socio-political nature of the community. The greatest variation was observed for the samples from Tell Brak and Tell Barri, the capital and the second-rank administrative centre, respectively. Although Tell Arbid showed less variability, some population segmentation was observed between different burial loci.

The Ypresian Cambay Shale Formation of Vastan Lignite Mine in Gujarat, western India, has yielded a rich vertebrate fauna, including the earliest modern mammals of the Indian subcontinent. Here we describe its assemblage of four frogs,including two new genera and species, based on numerous, diverse and well−preserved ilia and vertebrae. An abundant frog, Eobarbourula delfinoi gen. and sp. nov., with a particular vertebral articulation similar to a zygosphene−zygantrum complex, represents the oldest record of the Bombinatoridae and might have been capable of displaying the Unken reflex. The large non−fossorial pelobatid Eopelobates, known from complete skeletons from the Eocene and Oligocene of Europe, is also identified at Vastan based on a single nearly complete ilium. An abundant “ranid” and a possible rhacophorid Indorana prasadi gen. and sp. nov. represent the earliest records of both families. The Vastan pelobatids and ranids confirm an early worldwide distribution of these families, and the bombinatorids and rhacophorids show possible origins of those clades on the Indian subcontinent.
