This study uses DNA from museum hair samples to confirm Thomas Jefferson's ancestry in descendants of Sally Hemings and Martha Wayles Jefferson, supporting paternity over alternative explanations.

This study uses ancient and modern bison genomes to show past population connectivity and reveal human impacts on bison diversity, informing conservation efforts.

Angiosperms353 capture of Lake Elsinore sedimentary DNA recovers 50 land-plant orders across 24,000 years, with a fire-linked community shift preceding a persistent Holocene chaparral assemblage.

The paper uses ancient DNA from shells to analyze genetic stability and immune adaptation in black abalone post-bottleneck, finding delayed genomic erosion and rapid immune-related selection.

The paper analyzes the genomes of black abalone to assess genetic impacts of a population collapse and finds no spatial genetic structure, high genetic diversity, and low WS prevalence, suggesting translocation could aid recovery.

The paper reports a SARS-CoV-2 lineage with mutations from known variants of concern that is rejected by sequence repositories due to a deletion, suggesting underestimation of its frequency.

This study uses Early Pleistocene dental enamel proteome sequences to resolve the phylogeny of Stephanorhinus, showing it is paraphyletic and requiring systematic revision.

This paper analyzes ancient genomes from North Africa to show prehistoric migrations brought genetic influences from both the Levant and Europe to the Maghreb.
