Stone-age humans imported deer to remote Scottish islands
Wild animals were transported across land and sea to create a new resource
They analyzed DNA from deer bone from archaeological sites and discovered that the early deer on the islands were not related to any local groups - and seem likely to have come from continental Europe. This suggests that prehistoric humans transported the deer across land and sea to colonize the islands.
Once released and established, the deer would have been harvested for food, skin and especially antler and bone, which were valuable materials for making tools.
