The paper develops likelihood ratios for forensic DNA mixtures from shotgun sequencing data, showing they can be unreliable and proposing a combined evidence score to improve accuracy.

The paper identifies a plasmid, pTP33, unique to Second Pandemic Yersinia pestis strains, which may have increased transmission and mortality during that pandemic.

The paper investigates whether the spread of megaliths in Neolithic Europe was due to population movements or cultural diffusion, finding that both factors interacted through trade networks.

This study identifies the oldest known plague strains in Lake Baikal hunter-gatherers 5500 years ago, showing early outbreaks were lethal and challenged the idea that agriculture was necessary for plague epidemics.

ybyra assigns Y-chromosome haplogroups using a tree-based scoring method and supports human and horse data.

This study uses environmental DNA from Lake Tjornin to challenge the narrative of Norse-induced environmental collapse in Reykjavik, showing dynamic human-environment interactions shaped by both cultural practices and external stressors.

This study uses ancient genomic data to test models of Celtic language spread, finding support for a Central European origin linked to the Urnfield culture.

The paper uses ancient DNA and strontium isotope analyses to show a deep east-west divergence in steppe ancestry in Southern Europe, supporting specific linguistic divergence models for Indo-European languages.

The paper traces the evolutionary history of the CCR5delta32 deletion using ancient and modern genomes, finding it originated at least 7,000 years ago in Western Eurasia and underwent positive selection.

The study analyzes the genome of a late Neanderthal individual from France, revealing genetic isolation in his population despite geographic proximity to other late Neanderthals.

This study evaluates the accuracy of genotype imputation for ancient genomes and finds it comparable to modern DNA, with some population-specific biases.

This study uses multi-omics analysis of ancient human remains from Sicily to show genetic homogeneity and a diet rich in animal proteins during the Upper Palaeolithic.

This study analyzes ancient genomes from the Viking Age to understand genetic structure and migration patterns, finding significant foreign gene flow and population differentiation.

The paper sequences a 5,700-year-old human genome and oral microbiome from Stone Age chewing gum, revealing genetic and microbial insights.

The paper identifies a human accelerated region in Chromosome 14q12 that enhances forebrain expansion through increased enhancer activity in transgenic mice and organoids.

This paper analyzes ancient genomes from northeastern Siberia to reveal complex population migrations and admixture events over the past 40,000 years.

The paper analyzes the genome of a Jomon individual to infer migration patterns into East Asia, finding multiple waves and a coastal route from Southeast Asia.

The paper identifies targets of selection in the FADS region in Europeans, showing allele frequency changes linked to lipid-related phenotypes and dietary adaptations.
