      The Bering Land Bridge (BLB) last connected Eurasia and North America during the Late Pleistocene. Although the BLB would have enabled transfers of terrestrial biota in both directions, it also acted as an ecological filter whose permeability varied considerably over time. Here we explore the possible impacts of this ecological corridor on genetic diversity within, and connectivity among, populations ...

    • Evolutionary consequences of genomic deletions and insertions in the woolly mammoth genome 

      van der Valk, Tom; Dehasque, Marianne; Chacón-Duque, J. Camilo; Oskolkov, Nikolay; Vartanyan, Sergey; Heintzman, Peter D.; Pečnerová, Patrícia; Díez-del-Molino, David; Dalén, Love (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-01)
      Woolly mammoths had a set of adaptations that enabled them to thrive in the Arctic environment. Many mammoth-specific single nucleotide polymorphisms (SNPs) responsible for unique mammoth traits have been previously identified from ancient genomes. However, a multitude of other genetic variants likely contributed to woolly mammoth evolution. In this study, we sequenced two woolly mammoth genomes and ...
