The paper analyzes genetic ancestry of Afro-Puerto Ricans, revealing African origins similar to Lower Guinea and Bight of Biafra, and European origins similar to Iberian, Italian, and Basque populations.

The paper analyzes pre-Hispanic genetic data from Mexico to show population continuity despite climate change and identifies an ancient unsampled ghost population's contribution.

This study identifies clotting factor genes PROZ, F7, and F10 on chromosome 13 as associated with preeclampsia in high-altitude Andean families.

This study identifies loci under selection in Latin American admixed populations, distinguishing between pre- and post-admixture selection, and finds signals related to immunity and energy metabolism.

The paper identifies extensive methylation changes in genes related to facial and vocal anatomy in modern humans compared to ancient humans and chimpanzees.

This study uses ancient DNA to reconstruct the genetic legacies of pre-contact Puerto Rico communities, finding Native American mtDNA haplogroups and shared ancestry with the Bahamas.

This study applies Y-chromosome capture-enrichment to ancient DNA libraries, showing increased recovery of Y-DNA sequences and enabling haplogroup assignment.

This study compares two DNA extraction methods for ancient samples from tropical environments, finding Method D better for fragmented DNA recovery.
