Iberian Brown Bears

Iberian Brown Bears

The Iberian brown bears do not descend from those fled from the north during the Ice Age. According to the glacier refuges theory, after the last glaciations the bears of northern Europe sought shelter in the South. Researchers now reject this idea: they have reconstructed the colonization of brown bears in the Iberian Peninsula and have shown that the lineage of the Pleistocene bears was lost. Source 5e.
