About Deer
Deer anime - wallpapers: In "Origin of Species" (1859) Charles Darwin wrote Although I do not know of any thoroughly well-authenticated cases of perfectly fertile hybrid animals, I have some reason to believe that the hybrids from Cervulus vaginalis and Reevesii [...] are perfectly fertile. These two varieties of muntjac are currently considered the same species. A number of deer hybrids are bred to improve meat yield in farmed deer. Once considered separate species because of the great differences between them, American Elk (or Wapiti) and Red Deer from the Old World can produce fertile offspring, and are now considered one species. (The European Elk is a different species and is known as Moose in the USA.) The hybrids are about 30% more efficient in producing antler by comparing velvet to body weight. Wapiti have been introduced into some European Red Deer herds to improve the Red Deer type, but not always with the intended improvement. In New Zealand, where deer are introduced species, there are hybrid zones between Red Deer and North American Wapiti populations and also between Red Deer and Sika Deer populations. In New Zealand Red Deer have been artificially hybridized with Pere David Deer in order to create a farmed deer which gives birth in spring. The initial hybrids were created by artificial insemination and back-crossed to Red Deer. In Canada, the farming of European Red Deer and Red Deer hybrids is considered a threat to native Wapiti. In Britain, the introduced Sika Deer is considered a threat to native Red Deer. Initial Sika Deer/Red Deer hybrids occur when young Sika stags expand their range into established red deer areas and have no Sika hinds to mate with. They mate instead with young Red hinds and produce fertile hybrids. These hybrids mate with either Sika or Red Deer (depending which species is prevalent in the area), resulting in mongrelization. Many of the Sika Deer which escaped from British parks were probably already hybrids for this reason...
