Narrow-headed vole, together with collared lemming and common vole, was the most abundant small mammal species across Eurasian Late Pleistocene steppe-tundra environments. Previous ancient DNA studies of the latter two revealed dynamic past population histories shaped by climatic fluctuations. To investigate the extent to which species with similar adaptations share common evolutionary histories, we generated a dataset comprising mitochondrial genomes of 139 ancient and 6 modern narrow-headed voles from multiple sites across Europe and north-western Asia and covering the last ca. 100 thousand years (ka). We inferred Bayesian time-aware phylogenies using 11 radiocarbon-dated samples for calibration of the molecular clock. We found that across the three species, divergence of the main mtDNA lineages occurred during Marine Isotope Stages (MIS) 7 and MIS 5, suggesting a common response of species adapted to open habitat to the interglacial environments. In European narrow-headed voles, we identified multiple ... : MtDNA sequences from subfossil specimens were generated using target enrichment coupled with highthroughput sequencing. ...
