AB  - The combined actions of climatic variations and landscape barriers shape the history of natural populations. When
organisms follow their shifting niches, obstacles in the landscape can lead to the splitting of populations, on which
evolution will then act independently. When two such populations are reunited, secondary contact occurs in a broad
range of admixture patterns, from narrow hybrid zones to the complete dissolution of lineages. A previous study
suggested that barn owls colonized the Western Palearctic after the last glaciation in a ring-like fashion around the
Mediterranean Sea, and conjectured an admixture zone in the Balkans. Here, we take advantage of whole-genome
sequences of 94 individuals across the Western Palearctic to reveal the complex history of the species in the region
using observational and modeling approaches. Even though our results confirm that two distinct lineages colonized the
region, one in Europe and one in the Levant, they suggest that it predates the last glaciation and identify a secondary
contact zone between the two in Anatolia. We also show that barn owls recolonized Europe after the glaciation from
two distinct glacial refugia: a previously identified western one in Iberia and a new eastern one in Italy. Both glacial
lineages now communicate via eastern Europe, in a wide and permeable contact zone. This complex history of populations
enlightens the taxonomy of Tyto alba in the region, highlights the key role played by mountain ranges and
large water bodies as barriers and illustrates the power of population genomics in uncovering intricate demographic
patterns.
