This book was released on 2024-04-05 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Silk Road, a historical network of interlinking trade routes across the Afro-Eurasian landmass, was of great importance to the transport of peoples, goods, and ideas between the East and the West. Although its main use was for importing silk from China, traders moving in the opposite direction carried to Central China jewellery, glassware, and other exotic goods from the Mediterranean, jade from Khotan, and horses and furs from the nomads of the Steppe. The Silk Road brought together the achievements of the different peoples of Eurasia to advance the Old World as a whole.

Available in PDF, EPUB and Kindle. Book excerpt: The past few years have witnessed a revolution in our ability to obtain DNA from ancient humans. This important new data has added to our knowledge from archaeology and anthropology, helped resolve long-existing controversies, challenged long-held views, and thrown up remarkable surprises. The emerging picture is one of many waves of ancient human migrations, so that all populations living today are mixes of ancient ones, and often carry a genetic component from archaic humans. David Reich, whose team has been at the forefront of these discoveries, explains what genetics is telling us about ourselves and our complex and often surprising ancestry. Gone are old ideas of any kind of racial âpurity.' Instead, we are finding a rich variety of mixtures. Reich describes the cutting-edge findings from the past few years, and also considers the sensitivities involved in tracing ancestry, with science sometimes jostling with politics and tradition. He brings an important wider message: that we should recognize that every one of us is the result of a long history of migration and intermixing of ancient peoples, which we carry as ghosts in our DNA. What will we discover next?

Available in PDF, EPUB and Kindle. Book excerpt: Human Evolutionary Genetics is a groundbreaking text which for the first time brings together molecular genetics and genomics to the study of the origins and movements of human populations. Starting with an overview of molecular genomics for the non-specialist (which can be a useful review for those with a more genetic background), the book shows how data from the post-genomic era can be used to examine human origins and the human colonization of the planet, richly illustrated with genetic trees and global maps. For the first time in a textbook, the authors outline how genetic data and the understanding of our origins which emerges, can be applied to contemporary population analyses, including genealogies, forensics and medicine.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ancient DNA research in the past decade has revealed that European genetic population structure changed dramatically in the prehistoric period (14,000-3,000 years before present, YBP), reflecting the widespread introduction of Neolithic farmer and Bronze Age Steppe ancestries. However, little is known about how population structure changed in the historical period onward (3,000 YBP - present). This dissertation addresses this question through both spatial and temporal dimensions. First, we showed that the population in the city of Rome alone was highly dynamic over time, and remarkably heterogeneous at the height of the Roman Empire, including 40% of the population having Near Eastern ancestry. To understand the genetic structure of contemporaneous populations outside of Rome and how they interacted, we collected whole genomes from 204 European and Mediterranean individuals, many of which are the first historical period genomes from their region (e.g. Armenia, France). Similar to our findings in Rome, we found that most regions show remarkable inter-individual heterogeneity. Around 8% of historical individuals carry ancestry uncommon or non-existent in the region where they were sampled, some indicating cross-Mediterranean contacts. Despite this high level of mobility, overall population structure across western Eurasia is relatively stable through the historical period up to the present, mirroring the geographic map. We show that, under standard population genetics models with local panmixia, the observed level of dispersal would lead to a collapse of population structure. Persistent population structure thus suggests a lower effective migration rate than indicated by the observed dispersal. This phenomenon can be explained by extensive transient dispersal arising from drastically improved transportation networks and the Roman Empire's mobilization of people for trade, labor, and military. Together, these works highlight the utility of ancient DNA in elucidating finer scale human population dynamics in recent history.

Available in PDF, EPUB and Kindle. Book excerpt: The rise of the multi-billion dollar ancestry testing industry points to one immutable truth about us as human beings: we want to know where we come from and who our ancestors were. John H. Relethford and Deborah A. Bolnick explore this topic and many more in this second edition of Reflections of Our Past. Where did modern humans come from and how important are the biological differences among us? Are we descended from Neandertals? How should we understand the connections between genetic ancestry, race, and identity? Were Native Americans the first to inhabit the Americas? Can we see evidence of the Viking invasions of Ireland a millennium ago even in the Irish of today? Through engaging examination of issues such as these, and using non-technical language, Reflections of Our Past shows how anthropologists use genetic information to suggest answers to fundamental questions about human history. By looking at genetic variation in the world today and in the past, we can reconstruct the recent and remote events and processes that have created the variation we see, providing a fascinating reflection of our genetic past.

This book was released on 2018-06-05 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hailed as a breakthrough in the understanding of human evolution, The History and Geography of Human Genes offers the first full-scale reconstruction of where human populations originated and the paths by which they spread throughout the world. By mapping the worldwide geographic distribution of genes for over 110 traits in over 1800 primarily aboriginal populations, the authors charted migrations and devised a clock by which to date evolutionary history. This monumental work is now available in a more affordable paperback edition without the myriad illustrations and maps, but containing the full text and partial appendices of the authors' pathbreaking endeavor.

Available in PDF, EPUB and Kindle. Book excerpt: Human Population Genetics and Genomics provides researchers/students with knowledge on population genetics and relevant statistical approaches to help them become more effective users of modern genetic, genomic and statistical tools. In-depth chapters offer thorough discussions of systems of mating, genetic drift, gene flow and subdivided populations, human population history, genotype and phenotype, detecting selection, units and targets of natural selection, adaptation to temporally and spatially variable environments, selection in age-structured populations, and genomics and society. As human genetics and genomics research often employs tools and approaches derived from population genetics, this book helps users understand the basic principles of these tools. In addition, studies often employ statistical approaches and analysis, so an understanding of basic statistical theory is also needed. Comprehensively explains the use of population genetics and genomics in medical applications and research Discusses the relevance of population genetics and genomics to major social issues, including race and the dangers of modern eugenics proposals Provides an overview of how population genetics and genomics helps us understand where we came from as a species and how we evolved into who we are now

This book was released on 2021* with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Archaeogenetics is the research field of studying the genetic information contained in ancient DNA (aDNA) to gain insight into the past. Analysis of human aDNA from archaeological material has allowed archaeogeneticists to observe changes in the genetic composition of populations in an area through time. By using aDNA in this manner, a higher degree of resolution can be gained into the timing of past genetic transitions, compared to the resolution that is available when inferring the past from modern genomic data alone. In this thesis, I focus on the movement of genes, via migration of people and/or admixture, and the information that this movement can provide about human history. I introduce the differences between the inheritance mechanisms of uniparental (mitochondrial DNA and the Y-chromosome) and autosomal markers; the forces of evolution in population genetics; some methods commonly used in the analysis of human aDNA in the manuscripts included in this thesis; prior (archaeo-)genetics research regarding the population history of West Eurasia and the Americas -as context for my own research in these geographic areas-, and discuss the information gained by my own work about the population history of the areas studied, the limitations of archaeogenetic inferences, and the importance of combining archaeogenetic results with those from other disciplines when studying human history.

Download or read book Mitochondrial DNA in Ancient Human Populations of Europe written by Clio Der Sarkissian and published by . This book was released on 2011 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution of human genetic variability is the result of thousand years of human evolutionary and population history. Geographical variation in the non-recombining maternally inherited mitochondrial DNA has been studied in a wide array of modern populations in order to reconstruct the migrations that have participated in the spread of our ancestors on the planet. However, population genetic processes (e.g., replacement, genetic drift) can significantly bias the reconstruction and timing of past migratory and demographic events inferred from the analysis of modern-day marker distributions. This can lead to erroneous interpretations of ancient human population history, a problem that potentially could be circumvented by the direct assessment of genetic diversity in ancient humans. Despite important methodological problems associated with contamination and post-mortem degradation of ancient DNA, mitochondrial data have been previously obtained for a few spatially and temporally diverse European populations. Mitochondrial data revealed additional levels of complexity in the population history of Europeans that had remained unknown from the study of modern populations. This justifies the relevance of broadening the sampling of ancient mitochondrial DNA in both time and space. This study aims at filling gaps in the knowledge of the genetic history of eastern Europeans and of European genetic outliers, the Saami and the Sardinians. This study presents a significant extension to the knowledge of past human mitochondrial diversity. Ancient remains temporally-sampled from three groups of European populations have been examined: north east Europeans (200 - 8,000 years before present; N = 76), Iron Age Scythians of the Rostov area, Russia (2,300 - 2,600 years before present; N = 16), Bronze Age individuals of central Sardinia, Italy (3,200 - 3,400 years before present; N = 16). The genetic characterisation of these populations principally relied on sequencing of the mitochondrial control region and typing of single nucleotide polymorphisms in the coding region. Changes in mitochondrial DNA structure were tracked through time by comparing ancient and modern populations of Eurasia. Analysis of haplogroup data included principal component analysis, multidimensional scaling, fixation index computation and genetic distance mapping. Haplotypic data were compared by haplotype sharing analysis, phylogenetic networks, Analysis of the Molecular Variance and coalescent simulations. The sequencing of a whole mitochondrial genome in a north east European Mesolithic individual lead to defining a new branch within the human mitochondrial tree. This work presents direct evidence that Mesolithic eastern Europeans belonged to the same Palaeolithic/Mesolithic genetic background as central and northern Europeans. It was also shown that prehistoric eastern Europeans were the recipients of multiple migrations from the East in prehistory that had not been previously detected and/or timed on the basis of modern mtDNA data. Ancient DNA also provided insights in the genetic history of European genetic outliers; the Saami, whose ancestral population still remain unidentified, and the Sardinians, whose genetic differentiation is proposed to be the result of mating isolation since at least the Bronze Age. This study demonstrates the power of aDNA to reveal previously unknown population processes in the genetic history of modern Eurasians.
