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.
A study combining archaeology and genetics, published in Science, reveals that the spread of Neolithic practices from Anatolia wasn't solely due to migration. Researchers found evidence of significant genetic continuity in West Anatolia over 7,000 years, despite cultural shifts like the adoption of agriculture and settled lifestyles. This suggests ideas and technologies spread without large-scale population movement in many areas. Some regions did experience migration and genetic mixing around 7,000 BCE, and later in the Aegean, but the overall picture is one of cultural diffusion occurring alongside, and often independently of, population shifts. The study highlights the importance of supporting research in the regions directly related to the questions being investigated and demonstrates a new methodology for integrating genomic and archaeological data.
A new study suggests the European Huns shared a common language with the Xiongnu, indicating Siberian roots rather than Turkic origins. The research, based on linguistic evidence, archaeology, and genetics, points to a shared Yeniseian language family.
The Darwin's Cats project aims to create a comprehensive database of feline behaviors and genetics by collecting fur samples and surveys from cat owners.
New genetic research suggests that humans first developed language around 135,000 years ago, with its widespread social use around 100,000 years ago. This study, using data from 15 genetic studies, indicates that language likely began as a cognitive system before becoming crucial for social communication.
In a recent study by scientists at UC San Francisco, human accelerated regions (HARs) have been identified as crucial to the rapid evolution of human brain complexity, distinguishing us from our closest evolutionary relatives, chimpanzees. These regions, evolving 10 times faster than the typical mammalian rate, enable the formation of intricate neural networks, which support advanced cognitive functions.
A recent study in Frontiers in Neuroscience found that misophonia, a condition where certain sounds trigger intense emotional reactions, shares significant genetic overlap with psychiatric disorders like depression, anxiety, and PTSD.
"A particular genetic locus (rs2937573) was identified as being strongly associated with feeling intense rage triggered by the sound of chewing."
