In this review we summa.ized recent historica. records a.d molecula. studies on evolutiona.y history a.d phylogeogra.hy of Scots pine with focus on the Europea. highly fra.mented distribution a.ea.of the species. Fossilized pollen, pla.t micro- a.d ma.rofossil records provided evidences on the la.ge-sca.e species’ ra.ge shifts a.d demogra.hic cha.ges during the Qua.erna.y. Popula.ions of Scots pine were documented b.th in the gla.ia. (incl. full gla.ia.ion) a.d intergla.ia. periods.
