Author Correction: The genetic prehistory of the Baltic Sea region.

2018

While the series of events that shaped the transition between foraging societies and food producers are well described for Central and Southern Europe, genetic evidence from Northern Europe surrounding the Baltic Sea is still sparse. Here, we report genome-wide DNA data from 38 ancient North Europeans ranging from ~9500 to 2200 years before present. Our analysis provides genetic evidence that hunter-gatherers settled Scandinavia via two routes. We reveal that the first Scandinavian farmers derive their ancestry from Anatolia 1000 years earlier than previously demonstrated. The range of Mesolithic Western hunter-gatherers extended to the east of the Baltic Sea, where these populations persis…

Trans-ancestral GWAS of alcohol dependence reveals common genetic underpinnings with psychiatric disorders

2018

AbstractLiability to alcohol dependence (AD) is heritable, but little is known about its complex polygenic architecture or its genetic relationship with other disorders. To discover loci associated with AD and characterize the relationship between AD and other psychiatric and behavioral outcomes, we carried out the largest GWAS to date of DSM - IV diagnosed AD. Genome - wide data on 14,904 individuals with AD and 37,944 controls from 28 case / control and family - based studies were meta - analyzed, stratified by genetic ancestry (European, N = 46,568; African; N = 6,280). Independent, genome - wide significant effects of different ADH1B variants were identified in European (rs1229984; p = …

Evolutionary and phenotypic characterization of spike mutations in a new SARS-CoV-2 Lineage reveals two Variants of Interest

2021

Molecular epidemiology of SARS-CoV-2 aims to monitor the appearance of new variants with the potential to change the virulence or transmissibility of the virus. During the first year of SARS-CoV-2 evolution, numerous variants with possible public health impact have emerged. We have detected two mutations in the Spike protein at amino acid positions 1163 and 1167 that have appeared independently multiple times in different genetic backgrounds, indicating they may increase viral fitness. Interestingly, the majority of these sequences appear in transmission clusters, with the genotype encoding mutations at both positions increasing in frequency more than single-site mutants. This genetic outco…

Los orígenes biológicos y los derechos de hijos e hijas: filiación y derecho a saber | Biological Origins and the Rights of Children: Parentage and t…

2016

RESUMEN. Este trabajo tiene el proposito principal de estudiar como las nuevas formas de acceder a la paternidad y maternidad, a traves de las tecnicas de reproduccion asistida con donacion de gametos o embriones, afectan a algunos derechos de los hijos e hijas. En concreto, seran analizados los derechos de filiacion paterna y materna y el derecho a conocer los origenes biologicos. Para ello, sera central tomar en consideracion el deber que pesa sobre los poderes publicos de asegurar la proteccion integral de los hijos y posibilitar la investigacion de la paternidad, junto con el deber de los padres de prestar asistencia de todo orden a sus hijos. La igualdad de todos los hijos ante la ley,…

RESUMEN. La identificacion de la categoria "grupo desaventajado" o "grupo especialmente vulnerable" no es un tema resuelto desde el derecho anti-discriminatorio. Sin embargo, los inmigrantes pueden ser considerados facilmente en situacion de vulnerabilidad debido a las importantes restricciones de derechos sociales previstas en el marco normativo de extranjeria. En concreto, esta propuesta analiza las formas de categorizacion de los inmigrantes como potenciales sujetos vulnerables en diferentes contextos sureuropeos de crisis economica.  ABSTRACT. The identification of the category "disadvantaged group" or "particularly vulnerable group" is not a closed issue in the anti-discrimination law.…

Ancient DNA, Strontium isotopes, and osteological analyses shed light on social and kinship organization of the Later Stone Age.

2008

In 2005 four outstanding multiple burials were discovered near Eulau, Germany. The 4,600-year-old graves contained groups of adults and children buried facing each other. Skeletal and artifactual evidence and the simultaneous interment of the individuals suggest the supposed families fell victim to a violent event. In a multidisciplinary approach, archaeological, anthropological, geochemical (radiogenic isotopes), and molecular genetic (ancient DNA) methods were applied to these unique burials. Using autosomal, mitochondrial, and Y-chromosomal markers, we identified genetic kinship among the individuals. A direct child-parent relationship was detected in one burial, providing the oldest mol…

Tracing patterns of activity in the human skeleton: an overview of methods, problems, and limits of interpretation.

2009

Studies of patterns of activity in human skeletal remains have grown in number over the last few years. Different methods have been used to reconstruct activity patterns in past populations. In this review of the available literature the common themes of these studies have been isolated in order to show that many studies do not truly conform to the standards of the field. Inadequate sample size, too far-reaching conclusions and neglect of other possible explanations are among the problems easily recognised in the literature. Many assumptions are lacking a sound experimental basis, and it becomes increasingly evident that there are many more problems and limits of interpretations than have b…

Las exploraciones arqueológicas de 1930 en los túmulos de "La Mata" (Campanario, Badajoz)

2014

Before systematic excavation made between 1990-2002, the building Protohistoric of "La Mata" (Campanario, Badajoz) was a great mound of land known in the area with the expressive name place "Monton de Tierra Grande", to differentiate it from "Monton de Tierra Chico," a funerary monument and located almost 1 km Southeast of the first one. Both mounds were explored in early 1930 by Virgilio Viniegra Vera and John White Gallardo. These actions, although known, were insufficiently valued in our study of "La Mata" published in 2004 because this documentation wasn’t known to us. Recently we recovered a number of articles and news in the newspapers Correo Extremeno and Sol, that allowed to us to k…
