About 5,000 years ago, on Denmark’s Jutland Peninsula, wild boars were enjoying an unusual diet. Isotope analyses of wild board remains revealed that they were eating fish and other marine animals. The only way they could have gotten access to such food, researchers think, is if humans were deliberately feeding the boars seafood.
Why would they do that? Perhaps they used marine resources to domesticate the boars, a useful source of meat if they can be made tamer. Note that 5,000 years ago is before the agricultural revolution reached Denmark. So the locals were attempting animal domestication before they had adopted domesticated plants.
