Mouflon sheep. Mouflon have been introduced as game animals into Spieden Island in Washington state, and into the Hawaiian islands of Lanai and Hawaii where they have become a problematic invasive species. A small population escaped from an animal enclosure owned by Thomas Watson, Jr. on the island of North Haven, Maine in the 1990s and still survives there. Their normal habitats are steep mountainous woods near tree lines. In winter, they migrate to lower altitudes. The scientific classification of the mouflon is disputed. Five subspecies of mouflon are distinguished by MSW3: The eastern and the European mouflon often appear in
Domesticated red fox humans. Russian scientists achieved a population of domesticated foxes that are fundamentally different in temperament and behavior from their wild forebears. Some important changes in physiology and morphology became visible, such as mottled or spotted colored fur. Some scientists believe that these changes obtained from selection for tameness are caused by lower adrenaline production in the new population, causing physiological changes within relatively few generations yielding genetic combinations not present in the original species. This indicates that selection for tameness, e.g. did not flee, produces changes that are related to the emergence of other dog-like traits, e.g. raised tail, coming
