The South Asian subcontinent is characterized by a complex history of human migrations and population interactions. In this study, we used genome-wide data to provide novel insights on the demographic history and population relationships of six Indo-European populations from the Indian State of West Maharashtra. The samples correspond to two castes (Deshastha Brahmins and Kunbi Marathas) and four tribal groups (Kokana, Warli, Bhil and Pawara). We show that tribal groups have had much smaller effective population sizes than castes, and that genetic drift has had a higher impact in tribal populations. We also show clear affinities between the Bhil and Pawara tribes, and to a lesser extent, between the Warli and Kokana tribes. Our comparisons with available modern and ancient DNA datasets from South Asia indicate that the Brahmin caste has higher Ancient Iranian and Steppe pastoralist contributions than the Kunbi Marathas caste. Additionally, in contrast to the two castes, tribal groups have very high Ancient Ancestral South Indian (AASI) contributions. Indo-European tribal groups tend to have higher Steppe contributions than Dravidian tribal groups, providing further support for the hypothesis that Steppe pastoralists were the source of Indo-European languages in South Asia, as well as Europe.

Altitude adaptation in Tibetans caused by introgression of Denisovan-like DNA Huerta-Sanchez, Emilia; et. al. (Springer Science and Business Media LLC, 2014-08-14) As modern humans migrated out of Africa, they encountered many new environmental conditions, including greater temperature extremes, different pathogens and higher altitudes. These diverse environments are likely to have acted as agents of natural selection and to have led to local adaptations. One of the most celebrated examples in humans is the adaptation of Tibetans to the hypoxic environment of the high-altitude Tibetan plateau(1-3). A hypoxia pathway gene, EPAS1, was previously identified as having the...
Dataset on the Marine Sustainability in the United Arab Emirates Gülseven, Osman (Elsevier BV, 2020-08-01) This data compiles the relevant indicators on measuring the UAE's attainments towards sustaining marine life and coastal ecosystems. Those indicators are compiled from three databases, namely from the United Nations, BertelsmannStiftung (BS) Foundation, and the Ocean Health Index (OHI). While the UN and BS indicators are widely accepted in measuring sustainability, many of the indicators in these databases are ambiguous and incomplete. The data from OHI is complete and offers a better perspective on measuri...
Segregation dynamics with reinforcement learning and agent based modeling Sert, Egemen; Bar-Yam, Yaneer; Morales, Alfredo J. (Springer Science and Business Media LLC, 2020-7-16) Societies are complex. Properties of social systems can be explained by the interplay and weaving of individual actions. Rewards are key to understand people's choices and decisions. For instance, individual preferences of where to live may lead to the emergence of social segregation. In this paper, we combine Reinforcement Learning (RL) with Agent Based Modeling (ABM) in order to address the self-organizing dynamics of social segregation and explore the space of possibilities that emerge from considering d...
NEOGENE-RECENT SEDIMENTATION AND DEVELOPMENT OF THE ADANACILICIAN BASIN EVANS, G; GORUR, N; ALAVI, N (1988-08-01) The Adana-Cilician basin formed by interaction between the African, Arabian, and Anatolian plates. The basin has been filled asymmetrically from the north and northeast with the northeastern extremity having been completely filled to form the Adana basin beneath the plain of the Seyhan delta. There is no direct borehole evidence from the submarine areas, but coastal boreholes have revealed the presence of at least 6 km of Neogene sediment. The Burdigalian-Serravalian interval is dominated by turbidites and ...
Whole genome sequencing of Turkish genomes reveals functional private alleles and impact of genetic interactions with Europe, Asia and Africa Alkan, Can; Kavak, Pinar; Somel, Mehmet; Gokcumen, Omer; Ugurlu, Serkan; Saygi, Ceren; Dal, Elif; Bugra, Kuyas; GÜNGÖR, TUNGA; Sahinalp, S. Cenk; ÖZÖREN, NESRİN; BEKPEN, CEMALETTİN (2014-11-07) Background: Turkey is a crossroads of major population movements throughout history and has been a hotspot of cultural interactions. Several studies have investigated the complex population history of Turkey through a limited set of genetic markers. However, to date, there have been no studies to assess the genetic variation at the whole genome level using whole genome sequencing. Here, we present whole genome sequences of 16 Turkish individuals resequenced at high coverage (32 x -48x).
