Europe has played a major role in dog evolution, harbouring the oldest uncontested Palaeolithic remains and having been the centre of modern dog breed creation. Here we sequence the genomes of an Early and End Neolithic dog from Germany, including a sample associated with an early European farming community. Both dogs demonstrate continuity with each other and predominantly share ancestry with modern European dogs, contradicting a previously suggested Late Neolithic population replacement. We find no genetic evidence to support the recent hypothesis proposing dual origins of dog domestication. By calibrating the mutation rate using our oldest dog, we narrow the timing of dog domestication to 20,—40, years ago.

Misleading DNA Evidence: A Guide for Scientists, Judges, and Lawyers presents the reasons miscarriages of justice can occur when dealing with DNA, what the role of the forensic scientist is throughout the process, and how judges and lawyers can educate themselves about all of the possibilities to consider when dealing with cases that involve DNA evidence. DNA has become the gold standard by which a person can be placed at the scene of a crime, and the past decade has seen great advances in this powerful crime solving tool.

But the statistics that analysts can attach to DNA evidence often vary, and in some cases the statistical weight assigned to that match, can vary enormously. The numbers provided to juries often overstate the evidence, and can result in a wrongful conviction.

This resource is powered by the Protein Data Bank archive-information about the 3D shapes of proteins, nucleic acids, and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease. The RCSB PDB builds upon the data by creating tools and resources for research and education in molecular biology, structural biology, computational biology, and beyond.

Validation reports contain an assessment of the quality of a structure and highlight specific concerns by considering the coordinates of the model, the experimental data and the fit between the two. Easily interpretable summary information that compares the quality of a model with that of other models in the archive will help users of PDB data to critically assess archived entries and to select the most appropriate structural models for their needs. Validation reports for manuscript reviewers are created during annotation of deposited structures.

Deposit 3D macromolecular structure data to the PDB. From any page on the site, a Basic Search can be run by entering a search term in the top Search Bar. As you enter a term, you will see suggestions appearing in the dropdown menu that appears below the search bar.

Jewish, by comparison, is typically parsed as a religious or cultural identity. Isolation slowly narrowed the gene pool, which now gives modern Jews of European descent, like my family, a set of identifiable genetic variations that set them apart from other European populations at a microscopic level. This genetic explanation of my Ashkenazi Jewish ancestry came as no surprise. According to family lore, my forebears lived in small towns and villages in eastern Europe for at least a few hundred years, where they kept their traditions and married within the community, up until the Holocaust, when they were either murdered or dispersed.

The raw memory of this racism made any suggestion of Jewish ethnicity slightly taboo in my family.

So the Trojan Family is not just a metaphor. Turns out, we’re also linked by genetics more closely than previously thought. The assistant professor of computational biology ‘s background in math and statistics enables him to develop methods and models and perform data analysis on genomic data , which he applies to learn about evolution and demography. His latest research, which he conducted with Graham Coop, a geneticist at University of California, Davis—his former postdoctoral advisor—provided DNA-based evidence to confirm the mathematical theory that everyone on Earth is related.

Thus one can deduce that a lot of those ancestors must be the same person. A paper published in by Joseph Chang, a statistician at Yale University, analyzed this tapestry mathematically and concluded that we all share a common ancestor.
