G25 Studio: Beginner Manual
This guide is for people who are new to G25 coordinates and G25 Studio. It explains the ideas in plain language, walks through a simple first analysis, and points you to deeper documentation when you are ready.
G25 Studio: Algorithms, Distance Methods, and Oracle Settings
This document explains the configuration options available in G25 Studio in plain language. It covers the Monte Carlo algorithms, the Oracle (Ancestors Predictions) system, distance methods, and distance weights. Read this after you have completed at least one basic run.
Subsistence Shift Precedes Population Turnover in Eastern Andes
New ancient DNA analysis from the eastern Colombian Andes reveals five millennia of hunter-gatherer continuity, a sharp turnover with the Herrera culture, and maize adoption before population replacement—driven by migration and admixture rather than simple continuity.
Ibiza Medieval DNA Reveals Two-Pulse North African Admixture
New ancient genomes from Ibiza reveal a two-pulse North African admixture during the Islamic era, with Sub-Saharan links and diverse pathogens shaping Mediterranean population history.
Altai Ancient Genomes: Continuity, East Asian Admixture, ANE
New ancient genomes from the Altai region illuminate 1400 years of population continuity, East Asian admixture linked to Turkic expansion, and a novel ANE-linked lineage, reshaping our view of inner Eurasian history.
Genetic Insights into Native American Ancestry Across America
A Brazil-centered synthesis of Native American ancestry introducing a four-signature framework (witness, introduced, transplanted, new) to explain ancient migrations, admixture, and health implications.
Late Agricultural Adoption, Migration and Crisis in the Southern Andes
New ancient genomes and multi-proxy analyses illuminate a late farming frontier in the Southern Andes, revealing local continuity, migrant influx, maize-driven subsistence, and resilience strategies before the Inka expansion.
Ancient DNA reveals widespread directional selection in West Eurasia
A landmark ancient-DNA study analyzes 15,836 West Eurasians to detect sustained directional selection over 10,000 years, showing hundreds of allele changes and shifts in polygenic traits.
Ashkenazi Founder Event Pre-14th Century: Medieval DNA Insights
New genome-wide data from 14th-century Erfurt extends the Ashkenazi Jewish timeline, showing a founder event before the 1300s and revealing medieval genetic heterogeneity that shaped modern AJ.
Ancient DNA and Millet Diet in Bronze Age Northern China
New Bronze Age findings from Erdaojingzi reveal Central Plains–related ancestry and millet-based subsistence in northern China, using ancient DNA and isotopic evidence.
North African Maternal Diversity and Maghreb Gene Flow
New insights into North Africa’s maternal genetics from 869 complete mitogenomes across six populations reveal a cohesive Maghreb core, dominant haplogroups, and migration signals shaping regional ancestry.
Benchmarking Ancient DNA Kinship Methods with BADGER
BADGER benchmarks six ancient DNA kinship methods across coverage, damage, contamination, diversity, and inbreeding, revealing biases and guiding confident ancestry interpretations.
