Hidden Insights: Comprehensive Radiological Analysis of Four Skeletal Populations From 13th–19th Century Southern Finland Reveals Neoplastic and Other Lesions Invisible on Bone Surfaces

open access: yesInternational Journal of Osteoarchaeology, Volume 36, Issue 1, Page 196-206, January/February 2026.
ABSTRACT This study aims to identify lesions confined to the internal structures of bones. A radiographic analysis was performed on 219 archaeological, historical period skeletons from southern Finland. Although the study examines nearly all preserved skeletal elements using plain radiographs, it does not incorporate computed tomography.

Ostracod Genetic Variability in Response to Lake Level‐Driven Salinity Dynamics in Nam Co, Central Tibetan Plateau, in the Past Two Millennia

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Using sedimentary ancient DNA metabarcoding on a two‐millennia sediment core from Nam Co (Tibetan Plateau), the study reconstructs ostracod community shifts and genetic diversity in response to hydrological and climatic changes. Species richness peaked during moister intervals, while alternating dominance during the Medieval Climate Anomaly and Little ...

Paleogenetic Studies in Guajajara Skeletal Remains, Maranhão State, Brazil [PDF]

open access: yesJournal of Anthropology, 2014
In the early 17th century, French and Portuguese colonizers and Jesuit priests settled in the state of Maranhão and made contact with the Guajajara, an ethnic group that lived along the margins of the Pindaré River. The Guajajara maintained contact with Brazilian national society over the centuries, including with Brazilian admixed populations, and ...

Making vertebrate fossil radiocarbon dates more useful for global scientific research

open access: yesJournal of Quaternary Science, Volume 40, Issue 8, Page 1309-1335, November 2025.
ABSTRACT Radiocarbon dating of bones is essential for reconstructing timelines of species' occurrences, domestication, extinction, migrations, and interactions with Quaternary environments. Many studies compile these chronologies at continental to global scales by aggregating radiocarbon dates from various sources, often balancing data quantity and ...

Introducing FAMM: An Open‐Access Database of Fossil Arctic Marine Mammals

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 9, September 2025.
ABSTRACT Motivation The Arctic is currently experiencing the strongest effects of climate change on Earth. These effects, including sea ice loss, are already modifying the ecologies of the 11 species of marine mammals found in the Arctic year‐round.

Theoretical foundations for quantitative paleogenetics [PDF]

open access: yesJournal of Molecular Evolution, 1980
Theoretical equations are derived for molecular divergence with respect to gene and protein structure in the presence of genetic events with unequal probabilities: amino acid and base compositions, the frequencies of nucleotide replacements, the usage of degenerate codons, the distribution of fixed base replacements within codons and the distribution ...

Investigating Development in Human Evolution: Specificities, Challenges, and Opportunities

open access: yesEvolutionary Anthropology: Issues, News, and Reviews, Volume 34, Issue 1, March 2025.
ABSTRACT Unlike developmental biologists, paleoanthropologists primarily investigate development using skeletal remains, specifically fossilized and already‐formed bones and teeth. Focusing on peri‐ and/or postnatal growth, they reconstruct development from fragmented “snapshots” of individual trajectories at various ontogenetic stages.

Human Y chromosome haplogroup L1-M22 traces Neolithic expansion in West Asia and supports the Elamite and Dravidian connection

open access: yesiScience
Summary: West and South Asian populations profoundly influenced Eurasian genetic and cultural diversity. We investigate the genetic history of the Y chromosome haplogroup L1-M22, which, while prevalent in these regions, lacks in-depth study.

RRphylogeography: A new method to find the area of origin of species and the history of past contacts between species

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 3, Page 546-557, March 2025.
Abstract One of the main goals of historical biogeography is understanding where species originated, and how climate change and ecological interactions shaped their distribution. The task is complicated by both active and passive mechanisms, including habitat tracking, the separation of species into metapopulations of variably interconnected demes, and
