Extensive nuclear introgression accompanied ancient mitochondrial capture in the common ancestor of two sister hare species
Pleistocene climatic oscillations promoted contact and hybridization among hare species, leaving lasting genomic signatures. Two sister species, L. castroviejoi (broom hare, endemic to Iberia) and L. corsicanus (Italian hare, endemic to Italy), carry fixed mitogenomes from L. timidus (mountain hare), an Arctic species widespread in southern Europe before deglaciation. Whether such turnover was…
