European mouflon introduced into the Mediterranean basin in prehistoric times. According to some zoologists, the European mouflon is not a genuine game species, but a descendant of a very early race of domestic sheep. In fact, there are strong indications that European mouflon came to Corsica and Sardinia only some 7,000 years ago along with Neolithic peoples, since no traces can be found from earlier times. Over the last 200 years, European mouflon have been kept in various places in Europe. Prince Eugene of Savoy kept mouflon in his Viennese wildlife park, some of which were transferred to the Lainz Wildlife Park.
Species homogeneity calories. 95% of world consumption of protein derives from a few domesticated species, i.e. poultry, cattle and pigs. There are about 1,000 commercial fish species, but in aquaculture fewer than 10 species dominate global production. Human food production therefore rests on the tips of pyramids of biodiversity, leaving the majority of species not utilised and not domesticated. Species naturally migrate and expand their ranges, utilising new habitats and resources, e.g. the cattle egret. These natural invasions, an incursion in the absence of anthropogenic influences, occur "when an intervening barrier is removed, or through the development of biotic or abiotic transportation
