“…The migration through India was interrupted about 75 kya by the eruption of Mount Toba in Sumatra, Indonesia, which is recorded as one of the largest volcanic eruptions in this planet's history (Blinkhorn et al, 2014 ), resulting in an extended nuclear winter and ice age (Rampino and Self, 1993 ; Huang et al, 2001 ; Robock et al, 2009 ). Michael Petraglia and his team of archeologists discovered stone tools at Jwalapuram in Andhra Pradesh, South India, above and below a thick layer of ash from the Toba eruption (Petraglia et al, 2007 ).…”

Several studies have evaluated the movements of large populations to the Indian subcontinent; however, the ancient geographic origins of smaller ethnic communities are not clear. Although historians have attempted to identify the origins of some ethnic groups, the evidence is typically anecdotal and based upon what others have written before. In this study, recent developments in DNA science were assessed to provide a contemporary perspective by analyzing the Y chromosome haplogroups of some key ethnic groups and tracing their ancient geographical origins from genetic markers on the Y-DNA haplogroup tree. A total of 2,504 Y-DNA haplotypes, representing 50 different ethnic groups in the Indian subcontinent, were analyzed. The results identified 14 different haplogroups with 14 geographic origins for these people. Moreover, every ethnic group had representation in more than one haplogroup, indicating multiple geographic origins for these communities. The results also showed that despite their varied languages and cultural differences, most ethnic groups shared some common ancestors because of admixture in the past. These findings provide new insights into the ancient geographic origins of ethnic groups in the Indian subcontinent. With about 2,000 other ethnic groups and tribes in the region, it is expected that more scientific discoveries will follow, providing insights into how, from where, and when the ancestors of these people arrived in the subcontinent to create so many different communities.

“…Much more research is required before any conclusive or reliable statements can be made about the true short-or long-term impacts of Toba. For example, Blinkhorn et al (2014) have reported new YTT deposits in Sagileru Valley, where further multidisciplinary work can be carried out and where the methodological and interpretive errors made at Jwalapuram can be avoided. Unfortunately, virtually no Palaeolithic research has taken place in the other South Asian countries such as Nepal, Pakistan, Bangladesh, Bhutan and Sri Lanka; the majority of prehistoric research in these regions has centered on the Mesolithic and Neolithic evidence.…”

Fluvial sedimentary archives are important repositories for Lower and Middle Palaeolithic artefacts throughout the 'Old World', especially in Europe, where the beginning of their study coincided with the realisation that early humans were of great antiquity. Now that many river terrace sequences can be reliably dated and correlated with the globally valid marine isotope record, potentially useful patterns can be recognized in the distribution of the find-spots of the artefacts that constitute the large collections that were assembled during the years of manual gravel extraction. This paper reviews the advances during the past two decades in knowledge of hominin occupation based on artefact occurrences in fluvial contexts, in Europe, Asia and Africa. As such it is an update of a comparable review in 2007, at the end of IGCP Project no. 449, which had instigated the compilation of fluvial records from around the world during 2000e2004, under the auspices of the Fluvial Archives Group. An overarching finding is the confirmation of the well-established view that in Europe there is a demarcation between handaxe making in the west and flakeecore industries in the east, although on a wider scale that pattern is undermined by the increased numbers of Lower Palaeolithic bifaces now recognized in East Asia. It is also apparent that, although it seems to have appeared at different places and at different times in the later Lower Palaeolithic, the arrival of Levallois technology as a global phenomenon was similarly timed across the area occupied by Middle Pleistocene hominins, at around 0.3 Ma.

The presence of point blanks is more widespread, found not only in the sites yielding retouched points mentioned previously but also in Middle Palaeolithic sites, such as the Orsang Valley, 16R Dune, Site 55 and Bhimbetka (Ajithprasad 2005;Bednarik et al 2005;Blinkhorn 2013;Dennell et al 1992;Fig.…”

Examining the Origins of Hafting in South Asia

The appearance of hafting technologies marks a key shift in hominin behavioural evolution. Hafting first appears in Africa and Western Eurasia across the transition from Late Acheulean to Middle Palaeolithic technologies~300-200 thousand years ago (ka). Hafting technology in South Asia may have emerged as a result of a local innovation, through cultural diffusion or a population dispersal. The resolution of the South Asian Palaeolithic records has improved significantly over the past decade, enabling examination of patterns of change through time in stone tool technologies. Although functional studies of tool use remain limited in the region, a range of indices of hafting appear in stone tool assemblages that offer the first means to evaluate the origins of hafting in South Asia. Rare examples appear in Middle Pleistocene contexts, but indices of hafting appear repeatedly in Middle Palaeolithic assemblages dating within the past 100 thousand years and are commonplace amongst Late Palaeolithic assemblages dating within the past 45 thousand years. This dataset remains too immature to authoritatively resolve between alternate models for the origins of hafting, whereas direct association with discrete hominin populations is hampered by the region's scant fossil record. Nevertheless, this examination of the origin of hafting technology presents the means to reorient approaches to Late Pleistocene behavioural change in South Asia and integrate them within global debates regarding hominin innovation, demographic interaction and population expansion.
