This study reconstructs mitogenomes from ancient burials in Kashmir, revealing genetic continuity with local populations and evidence of contact with the Swat Valley and Central Asia.
Scientists have sequenced a complete genome from ancient Egypt, revealing the man's ancestry was mostly North African with a notable fraction from the Fertile Crescent, supporting a long-suspected cultural link.
Researchers at Michigan State University have uncovered a surprising mechanism that plants use to regulate their growth — one that directly ties their development to how they perceive light. They found a metabolic compound, naringenin chalcone, can 'reprogram' a UV light sensor, potentially leading to more resilient crops.
Genetic studies of human metabolism have been limited in scale and allelic breadth. Here we provide a data-driven map of the genetic regulation of circulating small molecules and lipoprotein characteristics (249 traits) measured using proton nuclear magnetic resonance spectroscopy across the allele frequency spectrum in ~450,000 individuals.
Geneticist David Reich explains how analyses made possible by technological advances show human history to be one of mixing, movement, and displacement.
This study identifies genetic factors associated with quantitative ability, using data from large-scale genome-wide association studies. The research reveals 53 SNPs linked to a latent trait, distinct from general intelligence, and implicates genes involved in neuron projection development and brain function.
Haplogroup Q-Y2197, also known as Haplogroup Q-M242, is a genealogical group of lineages defined by unique genetic markers present on the Y-chromosome. It's commonly found among populations in the United Kingdom and Ireland and is linked to the Marsh Arab population in Mesopotamia.
A pair of landmark studies has identified the originators of the Indo-European family of languages in current-day Russia about 6,500 years ago, the Caucasus Lower Volga people.
>“We can see there was a small group of villages 5,700 to 5,300 years ago with just a couple thousand breeding individuals,” Reich said. “And then there was a demographic explosion, with these people going everywhere.”

This page details the Y-DNA Haplogroup Q clusters found in the Ashkenazi Jewish population, including analysis of the Q-Y2198 and Q-YP1003 lineages, their estimated time to most recent common ancestor (TMRCA), and information on SNPs.
A new analysis of Indian genomes—the largest and most complete to date—helps untangle the groups' complex evolutionary history, uncovering a 50,000-year history of genetic mixing and population bottlenecks that shaped genetic variation, health and disease in South Asia.
