We further tested whether individuals included in the Vstonice and Fournol clusters share similar allele frequencies with the main representatives of those two clusters. Saag, L. et al. Earlier I had practiced a bit of MySQL, but here through this course I got introduced to PostgreSQL. Nat. Subsequently, I worked in bioinformatics for a year and then did my Masters in computer science (MCIT) at the University of Pennsylvania. 6 and Supplementary Fig. 38. Dotted lines delimit geographic regions described in the text. 276, 107319 (2022). The oldest individual revealing an indistinguishable genetic profile from the Yuzhniy Oleniy Ostrov group is the 11ka Sidelkino individual from Samara in western Russia42. We thus modelled individuals belonging to the GoyetQ2 cluster and El Mirn as a mixture between the Fournol 85 and Arene Candide 16 genomes as proxies to represent the Fournol and Villabruna ancestries, respectively, in Magdalenian-associated groups (Fig. AMAZING COURSE! Kumar, S., Stecher, G., Li, M., Knyaz, C. & Tamura, K. MEGA X: molecular evolutionary genetics analysis across computing platforms. The lsqproject: YES parameter was used to minimize the effect of missing data in ancient individuals. Inconsistent haplogroup assignments were manually verified as indicated24 (Supplementary Data 1.L). Tina Huang. Connect with them: Email: hellotinah@gmail.com. Branch labels show unique drift lengths; black dots refer to individuals with newly generated data and white dots refer topreviously published genomes;the position of each node does not imply the location where the split took place. Lifetime access to all course materials and updates. CAS Currently use of the word 'vape' now means "to inhale and exhale the vapor produced by an . A genome sequence from a modern human skull over 45,000 years old from Zlat k in Czechia. In this debated framework, Gravettian-associated individuals have been suggested to represent a biologically homogeneous population on the basis of craniometric and genomic data4,22. The genetic history of Ice Age Europe. Learn in-demand skills with a structured course that prepares you for the world of data science as it is today. A. Stoessel performed CT scanning and advised on sampling strategy. All individuals belonging to the Fournol cluster show higher affinity to Goyet Q116-1 than to the Sunghir group (n=4), and the Vstonice-cluster individuals show higher affinity to the Sunghir group than to Goyet Q116-1 (Extended Data Fig. ), no. (2023, March 1). In this period, the Oberkassel-ancestry admixture spread further east, reaching Samara by around 6.5ka, and an increase in Sidelkino ancestry was detected in hunter-gatherers from the Baltic region, which was previously associated with the transition from the Narva culture to the Comb Ceramic culture38,39 (Extended Data Fig. Quat. Evol. Moreover, two of the oldest published groups from western Russia belonging to the Sidelkino clusterPeschanitsa (13ka)43 and the newly reported Minino individuals (11ka)showed extra affinity to the Oberkassel cluster, possibly owing to variability in this ancestry proportion during the initial formation phase of the Sidelkino-ancestry profile. The newly reported individuals with over 15,000 SNPs on the Human Origins dataset are shown in black-outlined and filled symbols, as illustrated in the legend on the right, while representative ancient genomes are shown in outlined symbols, as illustrated in the legend at the bottom of the PCA. The mtDNA contamination was estimated by Schmutzi (--notusepredC --uselength)69 for all the libraries. Herein, methane is upgraded through the photocatalytic oxidative coupling of methane (OCM) over a ternary Ag-AgBr/TiO 2 catalyst in a pressurized flow reactor. Article 12). Hi, my name is Tina and I'm a data scientist at a FAANG company. Moreover, none of the Epigravettian-associated individuals have more affinity to southern European than to central-eastern European Gravettian-associated groups, as shown by f4(Mbuti, Epigravettian-associated individual/group; Vstonice, Paglicci 12) that is consistent with 0 (Supplementary Data 2.G). Zool. & Hlie, J. F. Temperature and precipitation regime in LGM human refugia of southwestern Europe inferred from 13C and 18O of large mammal remains. Data science is a lot like cooking. Definitely a course worth investing in as it sticks out as a unique course focusing on SQL interviews and doesn't contribute to the abundance of generic courses on the internet! Tina Llorca CPA, CWP, CEPP, CIS, MDRT Ampliar bsqueda. The genomic similarity of the Oberkassel cluster to Arene Candide 16 in northwestern Italy might imply that Epigravettian-associated ancestry spread from the south to central Europe passing through the western side of the Alpine region. The ethane yield of 35.4 mol/h with a high C 2 . Google Scholar. Financial support for ScienceDaily comes from advertisements and referral programs, where indicated. YOUTH VAPING: AN ANALYSIS OF AN EPIDEMIC 6 Youth Vaping: An Analysis of an Epidemic 'Vape.' In the 1980s, this was a phrase used to describe weapon uselimited primarily to science fiction writing. The triangles show the average calibrated dates of the tested groups and the dots show the estimated admixture dates with the software DATES105 using Oberkassel (red dots) or Villabruna (blue dots) clusters as one source and ANE-related individuals as the other source population. Here, data really gets to shine, in that its both the source of truth and the driver of insights. While terms such as lithic industry, techno-complex, prehistoric tradition, and so on might be more appropriate to refer to the various associated chrono-cultural subdivisions, they concern different levels of discussion and are not applicable to all contexts investigated here. Consultant - October 2015 to June 2016. Tina Huang. Biotechniques 59, 8793 (2015). Genome of Petera Muierii skull shows high diversity and low mutational load in pre-glacial Europe. The f4-statistics were calculated by qpDstat 755 with parameter f4 mode: YES, with the Mbuti.DG population from Africa used as outgroup in all f-statistics analyses. Save my name, email, and website in this browser for the next time I comment. Biol. Meyer, M. & Kircher, M. Illumina sequencing library preparation for highly multiplexed target capture and sequencing. Nucleic Acids Res. Jodie Sweetin. performed mortuary practices analyses. How to Rock at Data Science with Tina Huang, Older: Daily Habit #8: Math or Computer Science Exercise . Karmin, M. et al. We show that all analysed Epigravettian-associated individuals carry a homogeneous Villabruna ancestry, with the intra-group genetic structure mainly determined by their geographical, and not temporal, distribution. Overall, the Solutrean-associated Le Piage II individual links the preceding Fournol ancestry with the succeeding ancestry found in El Mirn, providing direct evidence for genetic continuity throughout the LGM in southwestern and western Europe. We love meeting interesting people and making new friends. Newsletter, I also have a newsletter called Boop's Keyboard! Google Scholar. 2c). Renaud, G., Slon, V., Duggan, A. T. & Kelso, J. Schmutzi: estimation of contamination and endogenous mitochondrial consensus calling for ancient DNA. (eds. Nat. Gravettian cranial morphology and human group affinities during the European Upper Palaeolithic. Jobs People Learning Dismiss Dismiss. 2022 Weird Science Plus - All Rights Reserved. Yang, M. A. et al. Article First, I like it because of how powerful (almost magical) it is in driving decisions. Feldman, M. et al. You also get a peek at Tina's Resume, so I don't think you want to miss out on that. This process allowed us to assign an ancestral or derived haplogroup for covered branches, and to make corrections to calls in cases where, for instance, a more derived haplogroup was called because of residual ancient damage (C-to-T or G-to-A mismatches) in terminal read positions at diagnostic SNPs98 (Supplementary Data 1.A). Genome sequence of a 45,000-year-old modern human from western Siberia. Evol. Individuals and groups are plotted with the same colours and symbols as in Fig. Consistent with previous findings, none of the analysed groups show the derived allele at SNP rs4988235 on the LCT gene, which is responsible for lactase persistence. It is often considered as a pan-European cultural mosaic with regional variations in material to symbolic productions20,21. This year they plan on seeing a total of 1,280 entries. EAGER: efficient ancient genome reconstruction. About the author: Tina Huang is a data scientist at one of the FAANG companies. A negative and cave bear positive controls were included. A phylogeographic reconstruction of different lineages carrying this ancestry further suggests its entry point into northeastern Italy from the Balkans followed by a north-to-south expansion into the Italian peninsula alongside a population decline through sequential bottlenecks. 9, 442 (2018).

Hi! Evol. She graduated with a degree in Computer Science and Applied Math. 2932 and Supplementary Table 4). Ancient admixture in human history. First, we show that individuals associated with the Gravettian culture across Europe were not a biologically homogeneous population. The detailed grouping of individuals shown with empty coloured circles is described in Supplementary Data 1.I. The tentative placements of low-coverage ancient individuals based on their haplogroup assignment (Supplementary Data 1.A) are indicated with arrows on the respective branches. The de-multiplexed capture sequencing reads were cleaned and mapped to human reference genome hs37d5 using EAGER pipeline 1.92.5564. Cosimo Posth, He Yu or Johannes Krause. Genomic data have shown that modern humans were present in western Eurasia1,2 at least 45ka. Paleogenomic evidence for multi-generational mixing between Neolithic farmers and Mesolithic hunter-gatherers in the Lower Danube Basin. . Curr. ), Science . The mitochondrial capture sequencing reads were cleaned by AdapterRemoval 2.2.0 to remove the adapters and reads with lengths below 30bp. In addition, those groups also carry affinity to ANF suggesting more complex genetic processes behind their demographic history16. and J.Krause performed or supervised genetic analyses. Tina teaches SQL in data science in addition to this basic material. Nature 505, 8791 (2014). USA 110, 22232227 (2013). Sci. 5, 820825 (2021). Despite this wide geographical range, it is not clear whether different groups associated with this culture originated from a common source population and how those groups were genetically related to each other. Individuals at this site might mark one of the last occurrences of such high levels of hunter-gatherer-related ancestries, just centuries before the emerging European Bronze Age. This free online conference is featuring panel discussions from 2011. Substantially contaminated libraries as well as marginally contaminated libraries of individually analysed genomes were filtered to maintain reads showing postmortem DNA damage (Methods and Supplementary Figs. ather than doing some data analysis or looking at trends, we wanted to dedicate this bulletin to seven women in tech, data, and science that you should know about. 19-78-10053). de Investigacin en Arqueologa y Patrimonio Histrico, University of Alicante, Sant Vicent del Raspeig, Alicante, Spain, Javier Fernndez-Lpez de Pablo&Magdalena Gmez-Puche, Amsterdam Centre of Ancient Studies and Archaeology, University of Amsterdam, Amsterdam, The Netherlands, Department of Anatomy, Histology and Anthropology, Faculty of Medicine, Vilnius University, Vilnius, Lithuania, Service Rgional de lArchologie de Bourgogne-Franche-Comt, Besanon Cedex, France, Laboratoire de Chrono-Environnement, UMR 6249 du CNRS, UFR des Sciences et Techniques, Besanon Cedex, France, Institute of Pre- and Protohistory, University of Tbingen, Tbingen, Germany, Department of Archeological Sciences, Thuringian State Office for Monuments Preservation and Archeology, Weimar, Germany, University of Bucharest, Faculty of Geology and Geophysics, Department of Geology, Bucharest, Romania, Institute for Advanced Studies in Levant Culture and Civilization, Bucharest, Romania, German Archaeological Institute, Berlin, Germany, Brandenburg Authorities for Heritage Management and Archaeological State Museum, Zossen, Germany, Institute for Pre- and Protohistory, Kiel University, Kiel, Germany, Institute of Archeology at Brno, Czech Academy of Sciences, Centre for Palaeolithic and Paleoanthropology, Brno, Czechia, Institute of Archaeology, Academy of Sciences of the Republic of Tatarstan, Kazan, Russia, Samara State University of Social Sciences and Education, Samara, Russia, Early Prehistory and Quaternary Ecology, Department of Geosciences, University of Tbingen, Tbingen, Germany, Paleoanthropology, Institute for Archaeological Sciences, Department of Geosciences, University of Tbingen, Tbingen, Germany, DFG Centre for Advanced Studies Words, Bones, Genes, Tools, University of Tbingen, Tbingen, Germany, Royal Belgian Institute of Natural Sciences, Brussels, Belgium, Institute of Archaeology Russian, Academy of Sciences, Moscow, Russia, School of Archaeology, University of Oxford, Oxford, UK, Peter the Great Museum of Anthropology and Ethnography (Kunstkamera), Russian Academy of Sciences, Saint Petersburg, Russia, Department of Cultures, University of Helsinki, Helsinki, Finland, Seminar for Pre- and Protohistory, Gttingen University, Gttingen, Germany, Lower Saxony State Service for Cultural Heritage, Hannover, Germany, Department of Human Genetics, Leiden University Medical Center, Leiden, The Netherlands, You can also search for this author in
