The Geographical Distribution of Lactose Tolerance‐Associated Alleles 13910*T and 13915*G Is Strongly Linked to Male Founder Events in Eurasia

American Journal of Human Biology, Volume 38, Issue 5, May 2026.
ABSTRACT Lactose tolerance (lactase persistence) represents a very progressive human adaptation, the origins of which remain incompletely understood. This study aims to examine the geographical distribution of the two alleles associated with lactose tolerance in Eurasia (13910*T and 13915*G) in relation to the main Y haplogroups and autosomal ancestry ...

Genomic and dietary discontinuities during the Mesolithic and Neolithic in Sicily

iScience, 2022
Summary: Sicily is a key region for understanding the agricultural transition in the Mediterranean because of its central position. Here, we present genomic and stable isotopic data for 19 prehistoric Sicilians covering the Mesolithic to Bronze Age ...

Sedimentary Metagenomics Reveal Avian Community Transitions From the Last Glacial Maximum to the Holocene

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We used sedimentary ancient DNA shotgun metagenomics to reconstruct past bird communities in northern high‐latitude environments. By using long time series and data collected across a large environmental gradient, we contributed in a unique and explorative way to the understanding of palaeoecological dynamics between birds and their habitat on the ...

PCR and paleogenetics: for best and for worst

, 2021
In the middle of the 1980s, extraction and analysis of DNA preserved in biologicalremains of the past yielded the first results, giving rise to a new scientific field, paleogenetics.Its first successes were obtained thanks to the advent of PCR.

Capture Probe, Metabarcoding, or Shotgun Sequencing: Which Best Reflects Local Vegetation?

Environmental DNA, Volume 8, Issue 2, March/April 2026.
This study compares three workflows for analyzing sedimentary ancient DNA: metabarcoding, capture probes, and shotgun sequencing. We compare taxa identified by each method from 18 lakes across northern Norway to the species recorded in vegetation surveys to quantify the sensitivity and accuracy of the three workflows. ABSTRACT Metabarcoding is the most

Family History in the Iberian Peninsula during Chalcolithic and Bronze Age: An Interpretation through the Genetic Analysis of Plural Burials

Genealogy
Throughout history, it has been observed that human populations have buried the deceased members of their communities following different patterns. During the Copper Age and the Bronze Age—periods on which this study focuses—in the northern sub-plateau ...

African Arowana Genome Provides Insights on Ancient Teleost Evolution

iScience, 2020
Summary: Osteoglossiformes is a basal clade of teleost, evolving since the Jurassic period. The genomes of Osteoglossiformes species would shed light on the evolution and adaptation of teleost.

Ecologies of Risk: Malaria and Settler Landscape Transformation in 19th‐Century Ontario

American Journal of Human Biology, Volume 38, Issue 1, January 2026.
ABSTRACT Objectives This study examines how settler‐driven environmental change shaped malaria transmission and mortality in 19th‐century southern Ontario. It aimed to understand the biosocial and ecological conditions that sustained endemic malaria in a temperate, colonial context.

Salmonella enterica from a soldier from the 1652 siege of Barcelona (Spain) supports historical transatlantic epidemic contacts

iScience, 2021
Summary: Ancient pathogen genomics is an emerging field allowing reconstruction of past epidemics. The demise of post-contact American populations may, at least in part, have been caused by paratyphoid fever brought by Europeans. We retrieved genome-wide

Commentary on Seersholm Et al.: Yersinia pestis Infection Is Not Synonymous With Deadly Plague in Neolithic Scandinavia

American Journal of Biological Anthropology, Volume 189, Issue 1, January 2026.
ABSTRACT Objectives Emerging genomic evidence has identified ancestral strains of Yersinia pestis in ancient human populations, which has sparked debates about its pathogenic role in later Neolithic societies. Here, we review published evidence linking anthropological and biological data reflecting the past natural history of Y.
