We give uncalibrated dates in radiocarbon years (“bp”). We give calibrated dates in years before the common era, converting from uncalibrated to calibrated dates using IntCal131 and OxCal4.22 (https://c14.arch.ox.ac.uk/oxcal/OxCal.html). We indicate dates obtained directly on the skeleton for which we obtained ancient DNA by the suffix “calBCE”. We indicate indirect dates obtained based on archaeological context as “BCE”. Iran Hotu Cave (Iran) Hotu Cave is located in the foothills of the Alborz Mountains, near the modern town of Behshahr on the southern shore of the Caspian Sea in northern Iran. The site was excavated to a depth of 12 meters by the American physical anthropologist Carleton Coon in the spring of 1951, and provides evidence of human occupation at various times from the early Mesolithic to the post-Achaemenid periods3-5. Skeletal remains of three sets of individuals (I, II, III) were recovered from Pleistocene Gravel 4 of Trench D, the deepest sounding undertaken (Section 2)3. In Coon’s preliminary excavation report, this gravel was initially identified as an aceramic Neolithic level, but was subsequently reclassified as a Mesolithic horizon.1,2,3 In 1955, two charcoal samples recovered in association with the skeletal remains from depths of 9.5 and 10.15 meters yielded uncalibrated radiocarbon ages of 9190±590 bp and 9270±570 bp respectively6. In 2013, AMS analyses of collagen extracted from a tooth from Mesolithic skeleton I yielded an uncalibrated radiocarbon age of 9480±40 bp (9119-8637 calBCE)7. The set III of individuals includes one adult partially complete skeleton (HotuIIIa) and the remains of a young child estimated to be 1.5-2 years old (HotuIIIb). We sampled the right petrous bone of HotuIIIb for DNA analysis. Subsequent AMS analysis of this specimen yielded an uncalibrated radiocarbon age of 7250 ± 40 bp (6218-6034 calBCE). The discrepancy in the direct dates of skeletal remains (Hotu I and IIIb) recovered from such close proximity to one another in the same archaeological horizon causes us to doubt the age of the Hotu IIIb specimen. There are no stratigraphic unconformities indicating that this specimen may have been introduced from overlying Neolithic cave deposits, and we suspect that the later than anticipated date may result from the use of modern-day organic materials such as the shellac or glue in post-excavation reconstruction of the Hotu IIIb crania. Genetic similarities between the CHG and Hotu IIIb specimens demonstrate that there are continuities between Iranian Neolithic 2 WWW.NATURE.COM/NATURE | 2 doi:10.1038/nature19310 RESEARCH SUPPLEMENTARY INFORMATION populations and local hunter-gatherer groups in northern Iran and the Caucasus, rather than with Epipalaeolithic or Neolithic populations originating in Anatolia or the Levant. The earlier date (9119- 8637 BCE)8 obtained from the Hotu I skeleton is not essential to support this observation, as the continuity of Iran Neolithic with hunter-gatherers of the southern Caucasus/Iran highlands rather than with those of the Levant is evident when either the HotuIIIb specimen or the securely dated pre- Neolithic Caucasus hunter-gatherers8 from Georgia are used (main text). We show a conservatively wide range that includes both the earliest date from Hotu I and the later direct date from HotuIIIb in Fig. 1a, although based on the arguments made here we strongly favor the earlier date and Mesolithic attribution of the HotuIIIb individual. • HotuIIIb (I1293): 1.5-2 year old individual. Ganj Dareh (Iran) Tepe Ganj Dareh is a mound on the floor of the Gamas-Ab Valley, and is situated at an altitude of ~1,400 meters in the High Zagros region of Kermanshah Province in western Iran. It is one of several mounds discovered during survey work in the area9. It measures about 40 meters in diameter and 7 to 8 meters in height and has five identified levels (A to E), with the lowest level E being the oldest. Permanent architecture is seen earliest at level D. Philip E. L. Smith led an excavation of roughly 20% of the mound in four seasons between 1967 and 1974. Zooarchaeological and archaeobotanical evidence show a population exploiting ovicaprids, with goats dominant, as well as evidence for use of wild barley but no plant domesticates. There is evidence of herding but no evidence for decreased size or changes in horn core morphology10,11. Current evidence places the occupation of the site at approximately 8000-7700 calBCE11. None of the human remains have been directly dated. The human remains are highly fragmentary. The current minimum number of individual is 116, of which 56 are catalogued as skeletons each represented by more than 4 elements12. The following six Ganj Dareh individuals (all petrous bone samples) are included in this study: • GD13A (I1290): 30-50 year-old female from level C. • GD14B (I1944): 3-4 year-old child from level B1. • GD16 (I1945): 5.5-7.5 year-old child from level D. • GD37 (I1949): 30-50 year-old male from levels D/E. • GD39 (I1951): 1.5-2.5 year-old child from level D crypt. • GD1150 (I1955): 18-30 year-old male from levels A/D. This individual is a clear genetic outlier and was analyzed separately from the other individuals pending radiocarbon dating, which confirmed that it was not from the Neolithic period but of recent origin (1430-1485 calCE (330±30 BP, Beta- 432801); it is thus labeled Iran_recent. 3 WWW.NATURE.COM/NATURE | 3 doi:10.1038/nature19310 RESEARCH SUPPLEMENTARY INFORMATION Seh Gabi (Iran) The site of Seh Gabi is a series of seven small mounds, identified as A through G, on a branch of the Gamas Ab River in the Kangavar Valley of the High Zagros region of Kermanshah Province, western Iran, about 6 kilometers from the much larger Chalcolithic and Bronze Age site of Godin Tepe. The mounds were scattered over an area of ~15 hectares with four excavated by Louis D. Levine and the Royal Ontario Museum between 1971 and 1973. Occupation lasted from the Late Neolithic through the Chalcolithic periods13. The human material, recovered in 1971 and 1973, comprises a minimum of 31 individuals that are almost entirely subadults: fetuses, infants and children <4 years of age; many with evidence of pathology. We report ancient DNA data on six samples (all petrous bones) from Mound A (n=2), Mound B (n=3), and Mound C (n=1). No radiocarbon dates have been obtained on Mound A, and so we use archaeological dates for the Chalcolithic of 4500-3500 BCE. Radiocarbon dates have been obtained from Mound B although not on the skeletons for which we report DNA. The dates obtained range from 5630±80 bp (SI-4915) to 5020±70 bp (SI-4910), and hence we represent the dates for samples from this bound by the union of the 95.4% calibrated confidence intervals (4680-3662 calBCE14,15). We directly dated the Mound C individual who is Late Neolithic: • SG19 (I1665): fetal remains, ~26 weeks old from Mound A. • SG21 (I1674): fetal remains, ~35 weeks old from Mound A. • SG7 (I1662): fetal remains, ~34 weeks old from Mound B. • SG11 (I1670): ~6 month-old infant from Mound B. • SG16 (I1661): ~9 months old infant from Mound B. • SG2 (I1671): 5837-5659 calBCE (OxA-33168, 6850±40 bp). ~6 month-old infant from Mound C. Levant Raqefet Cave (Israel) Raqefet Cave is located within a southern extension of Mt. Carmel. It has a long prehistoric sequence spanning the Middle Palaeolithic through to the Neolithic periods16. The first excavation was led by Noy and Higgs (1970-1972), and the most recent excavation was led by Nadel and Lengyel (2004- 2011). The first chamber was used extensively by the Natufians, who left on the terrace 100 bedrock mortars, cupmarks and cupules17. Some of the mortars are among the largest ever recorded for Natufian sites18, and one of the deepest has a grid-like pattern incised inside the shaft19. The samples we analyze for ancient DNA (all of which are petrous bones) were found in single or double primary burials lying on their back or on their side in flexed positions. These are part of a cluster of Natufian graves created within a short time span in a dedicated area of the first chamber of the cave. The area 4 WWW.NATURE.COM/NATURE | 4 doi:10.1038/nature19310 RESEARCH SUPPLEMENTARY INFORMATION contains approximately 30 human skeletons, all but one of which are in an area of about 15 meters squared.

ABSTRACT A long season of excavation took place at Raqefet cave during the summer of 2006. In the first chamber we exposed an area rich with Natufian human burials (Locus 1), a large bedrock basin with a burial and two boulder mortars (Locus 2), an in situ Natufian layer (Locus 3), and two areas with rich cemented sediments (tufa) covering the cave floor (Loci 4, 5). The latter indicate that at the time of occupation the Natufian layers covered the entire floor of the first chamber.

Gasparyan, Archaeology, Institute of Archaeology & Ethnography, ARMENIA For more than a century numerous archaeological sites attributed to the Middle Paleolithic have been investigated in the Southern Caucasus, but to date few have been excavated, analyzed, or dated using modern techniques. Thus only a handful of sites provide the contextual data necessary to address evolutionary questions regarding regional hominin adaptations and life-ways. This talk will consider current archaeological research in the Southern Caucasus, specifically that being conducted in the Republic of Armenia. While the relative frequency of well-studied Middle Paleolithic sites in the Southern Caucasus is low, those considered in this talk, Nor Geghi 1 (late Middle Pleistocene) and Lusakert Cave 1 (Upper Pleistocene), span a variety of environmental, temporal, and cultural contexts that provide fragmentary glimpses into what were complex and evolving patterns of subsistence, settlement, and mobility over the last ~200,000 years. While a sample of two sites is too small to attempt a serious reconstruction of Middle Paleolithic life-ways across such a vast and environmentally diverse region, the sites

  • A Longitudinal Genetic Survey Identifies Temporal Shifts in the Population

All rights reserved 0018-067X/16 www.nature.com/hdy ORIGINAL ARTICLE A longitudinal genetic survey identifies temporal shifts in the population structure of Dutch house sparrows L Cousseau1, M Husemann2, R Foppen3,4, C Vangestel1,5 and L Lens1 Dutch house sparrow (Passer domesticus) densities dropped by nearly 50% since the early 1980s, and similar collapses in population sizes have been reported across Europe. Whether, and to what extent, such relatively recent demographic changes are accompanied by concomitant shifts in the genetic population structure of this species needs further investigation. Therefore, we here explore temporal shifts in genetic diversity, genetic structure and effective sizes of seven Dutch house sparrow populations. To allow the most powerful statistical inference, historical populations were resampled at identical locations and each individual bird was genotyped using nine polymorphic microsatellites. Although the demographic history was not reflected by a reduction in genetic diversity, levels of genetic differentiation increased over time, and the original, panmictic population (inferred from the museum samples) diverged into two distinct genetic clusters. Reductions in census size were supported by a substantial reduction in effective population size, although to a smaller extent. As most studies of contemporary house sparrow populations have been unable to identify genetic signatures of recent population declines, results of this study underpin the importance of longitudinal genetic surveys to unravel cryptic genetic patterns.

  • The Pioneer Settlement of Modern Humans in Asia
    Nucleic Acids and Molecular Biology, Vol. 18 Hans-Jürgen Bandelt, Vincent Macaulay, Martin Richards (Eds.) Human Mitochondrial DNA and the Evolution of Homo sapiens © Springer-Verlag Berlin Heidelberg 2006 The Pioneer Settlement of Modern Humans in Asia Mait Metspalu (u) · Toomas Kivisild · Hans-Jürgen Bandelt · Martin Richards · Richard Villems Institute of Molecular and Cell Biology, Tartu University and Estonian Biocentre, Riia 23, Tartu, Estonia [email protected] 1 Introduction Different hypotheses, routes, and the timing of the out-of-Africa migration are the focus of another chapter of this book (Chap. 10). However, in order to dig more deeply into discussions about pioneer settlement of Asia, it is necessary to emphasize here that many recent genetic, archaeological, and anthropological studies have started to favour the Southern Coastal Route (SCR) concept as the main mechanism of the primary settlement of Asia (Lahr and Foley 1994; Quintana-Murci et al. 1999; Stringer 2000; Kivisild et al. 2003, 2004); see also Oppenheimer (2003). The coastal habitat as the medium for humans to penetrate from East Africa to Asia and Australasia was perhaps first envisaged by the evolution- ary geographer Carl Sauer, who considered the populations taking this route as adapted to the ecological niche of the seashore (Sauer 1962). After reach- ing Southwest Asia, modern humans had a choice of two potential routes by which to colonize the rest of Asia. These two were separated by the world’s mightiest mountain system—the Himalayas. The pioneer settlers could con- tinue taking the SCR or they could change their habitat and turn instead to the north, passing through Central Asia and southern Siberia (or via the route that later became known as the Silk Road).

In this study, we report novel genome-wide data for 763 individuals from Armenia, Georgia, Kazakhstan, Moldova, Mongolia, Russia, Tajikistan, Ukraine and Uzbekistan. We furthermore report additional damage-reduced genome-wide data of two previously published individuals from the Eneolithic Botai culture in Kazakhstan (~5,400 BP). We find that present-day inner Eurasian populations are structured into three distinct admixture clines stretching between various western and eastern Eurasian ancestries, mirroring geography. The Botai and more recent ancient genomes from Siberia show a decrease in contributions from so-called ‘ancient North Eurasian’ ancestry over time, which is detectable only in the northern-most ‘forest-tundra’ cline.

Associate Editor: Abstract We present a new Bayesian method for estimating demographic and phylogenetic history using population genomic data. Several key innovations are introduced that allow the study of diverse models within an Isolation with Migration framework. For the Markov chain Monte Carlo (MCMC) phase of the analysis, we use a reduced state space, consisting of simple coalescent trees without migration paths, and a simple importance sampling distribution without demography. Migration paths are analytically integrated using a Markov chain as a representation of genealogy. The new method is scalable to a large number of loci with excellent MCMC mixing properties. Once obtained, a single sample of trees is used to calculate the joint posterior density for model parameters under multiple diverse demographic models, without having to repeat MCMC runs. As implemented in the computer program MIST, we demonstrate the accuracy, scalability and other advantages of the new method using simulated data and DNA sequences of two common chimpanzee subspecies: Pan troglodytes troglodytes (P.

KEY WORDS: DEMOGRAPHY, ARCHAIC HUMANS, PSMC, GENE FLOW, POPULATION GROWTH Abstract Human populations have a complex history of introgression and of changing population size. Human genetic variation has been affected by both these processes, so that inference of past population size depends upon the pattern of gene flow and introgression among past populations. One remarkable aspect of human population history as inferred from genetics is a consistent “wave” of larger effective population size, found in both African and non-African populations, that appears to reflect events prior to the last 100,000 years. Here I carry out a series of simulations to investigate how introgression and gene flow from genetically divergent ancestral populations affect the inference of ancestral effective population size.
