Mouflon and being black on the shoulders. In Corsica this animal is named Mufro. Pallas, grouping goats and sheep together into a single genus "Aegoceros", distinguished the mouflon from the argali at species level in 1811 ("Ae. musimon" and "Ae. argali" respectively). In 1840 Blyth proposed that the Armenian and Cypriot sheep were also separate species, which he named "Ovis Gmelinii" (after "the younger Gmelin") and "O. Ophion" (from a name recorded by Pliny). Current taxonomy in some sources such as MSW and ITIS treats the mouflons and urials as subspecies of the domestic sheep, "Ovis aries" Linn. 1758. However ICZN
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
