Inferring Migration Networks with Time-Lagged F2 Statistics

The paper develops a method to infer directional migration rates from ancient DNA data using time-dependent F2 statistics, revealing an ancient pan-European migration network.

Exploring the Evolution of the Cariogenic Oral Pathobiont Streptococcus mutans Using Ancient DNA

This study uses ancient DNA to analyze the evolution of Streptococcus mutans over 8,000 years, showing that some virulence traits emerged with agricultural diets.

High resolution analysis of population structure using rare variants

This paper introduces RAS, a statistical method for analyzing rare variants to detect population structure with higher resolution than common variants, and demonstrates its improved accuracy in ancestry proportion estimation.

Bronze Age Northern Eurasian Genetics in the Context of Development of Metallurgy and Siberian Ancestry

This study analyzes the genetic profiles of Bronze Age metallurgical individuals to explore genetic heterogeneity and the spread of Siberian ancestry across Northern Eurasia.

Poseidon - A framework for archaeogenetic human genotype data management

Poseidon provides a framework for managing archaeogenetic data to ensure FAIR principles through open, interoperable tools and archives.

Estimating human mobility in Holocene Western Eurasia with large-scale ancient genomic data

The paper introduces an algorithm to estimate past human mobility using ancient genomic data from Western Eurasia over the last 10,000 years, revealing new movement patterns beyond known historical events.

Genome-wide data from medieval German Jews show that the Ashkenazi founder event pre-dated the 14th century

The paper analyzes genome-wide data from medieval German Jews to show the Ashkenazi founder event occurred before the 14th century, with genetic heterogeneity not present in modern Ashkenazi Jews.

Demes: a standard format for demographic models

The paper introduces Demes, a standard format for demographic models in population genetics to improve clarity and ease of use in simulations and analysis.

A dynamic 6,000-year genetic history of Eurasia's Eastern Steppe

This study reconstructs the 6,000-year genetic history of the Eastern Steppe using ancient genomes, revealing pastoralist expansions, population structuring, and the emergence of the Xiongnu and Mongols.

The genomic formation of First American ancestors in East and Northeast Asia

The paper shows Ancient Beringians have admixture from Amur River Basin populations and are not the deepest American lineage.

The Genomic Formation of Human Populations in East Asia

This paper uses ancient and present-day genomic data to reconstruct the population history of East Asia, identifying key migrations and language dispersals.

Genomic and dietary transitions during the Mesolithic and Early Neolithic in Sicily

Genome-wide and isotopic data from prehistoric Sicilians reveal a pre-farming connection to (south-) eastern Europe, and tentative initial evidence that hunter-gatherers adopted some Neolithic aspects prior to near-total replacement by early farmers.

The genetic prehistory of the Greater Caucasus

The paper analyzes genetic data from prehistoric individuals in the North Caucasus to explore the origins of Eurasian steppe ancestry and its relationship to cultural innovations.

Ancient Fennoscandian genomes reveal origin and spread of Siberian ancestry in Europe

The paper analyzes ancient genomes from Finland and Northwest Russia to show Siberian ancestry in northern Europe dates back 3,500 years and influenced modern Uralic-speaking populations.

Characterizing the genetic history of admixture across inner Eurasia

This study analyzes genome-wide data from inner Eurasian populations to characterize genetic admixture patterns and their historical context.

The asexual genome of Drosophila

The paper shows that the Drosophila genome has two modes of evolution: one with limited linkage effects and one with clonal competition, linked to recombination rates.

Paleo-Eskimo genetic legacy across North America

The paper analyzes ancient and present-day genome-wide data to show widespread Paleo-Eskimo ancestry among Na-Dene and Eskimo-Aleut language speakers and presents a model for North America's peopling.

The Genetic History of Northern Europe

This paper presents ancient DNA data from Northern Europe to reconstruct the genetic history of the region, showing earlier Anatolian farmer ancestry and the impact of steppe pastoralists.

Iron Age and Anglo-Saxon genomes from East England reveal British migration history

The paper analyzes ancient genomes from Iron Age and Anglo-Saxon periods in East England to estimate the genetic impact of migrations on modern British populations.

Rate and cost of adaptation in the Drosophila genome

The paper investigates how recombination rates influence adaptive evolution in Drosophila, finding higher adaptive substitution rates in high-recombining regions and significant collateral fitness costs in low-recombining regions.

Inferring human population size and separation history from multiple genome sequences

This paper introduces a method to infer human population size and separation history using multiple genome sequences, revealing ancient genetic splits and recent population events.
