What is Mitochondrial and nuclear DNA phylogeography of Thymallus spp. (grayling) provides evidence of ice‐age mediated environmental perturbations in the world's oldest body of fresh water, Lake Baikal about?

## Abstract Theories on the hydrological history of Lake Baikal, the world's oldest and deepest body of freshwater, and its surrounding great rivers, are currently based solely on geological evidence and are conflicting. Baikal is inhabited by numerous zoogeographical enigmas but their high level of endemism has hindered phylogeographic inferences. We provide a biological perspective of the region's palaeo‐hydrological development based on the demographic and genealogical history of the widespread __Thymallus__ spp. (grayling). Phylogenetic reconstruction reveals that old lineages of grayling (pre‐Pleistocene) currently inhabit the Enisey, Lena and Amur River basins. For Lake Baikal however, we conclude that a mid‐Pleistocene colonization (110 000–450 000 years ago) of an unoccupied niche has occurred. Population genetic inferences support an Enisey–Angara river route of colonization into Baikal, corresponding to the cataclysmic palaeo‐hydrological event that led to the formation of the lake's only contemporary outlet, and a subsequent range expansion several thousand kilometres into the uppermost reaches of the Selenga River basin. The evolutionary history of Lake Baikal grayling
