This study analyzes 68 ancient Portuguese genomes over 5,000 years, revealing migration patterns and genetic continuity, with influences from local, African, and Mediterranean populations.

This study evaluates qpAdm's performance on complex admixture histories and stepping-stone landscapes, finding high false discovery rates and suggesting protocol improvements.

This study evaluates the performance of qpAdm and f3-statistic in admixture inference under historical and ancient DNA conditions, showing limitations in resolving fine-scale hypotheses but potential for improvement with better f-statistic methods.

This study evaluates the effectiveness of the Twist Ancient DNA reagent for enriching ancient human SNPs, finding it robust for up to 27% endogenous DNA content with two rounds of enrichment.

This study models the Neolithic expansion in Europe, finding limited cultural transmission and predominant within-group mating, challenging assumptions about demic diffusion.

The paper identifies a systematic bias in in-solution enrichment of ancient human DNA using the Prime Plus kit, affecting population genetics inferences and genetic relatedness.
