All breeds of dogs are the result of the convergence of the factors of evolution and interbreeding. Some breeds are manmade, and some are naturally there is practically no influence on its form and function of the ability of natural selection. For example, the Bulldog breed was a "backward" caste and race to create a long-legged, more animated version of the original dog breed.

Tibetan breeds, the Lhasa Apso, Tibetan terrier, is more a product of evolution rather than human influence. Of the five recognized breeds Tibetan, Tibetan Terrier, Tibetan Spaniel, Do-khyi (Tibetan Mastiff), Lhasa Apso and Shih Tzu, Lhasa race is more directly influenced by the harsh climatic conditions Himalayas of Tibet.

There are many reasons why this happened. First Instead, Tibetans began to selectively breed only the Lhasa around 800 years ago in the city of Lhasa, capital and seat of the Dalai Lamas. However, the race has its origins about 2,000 years ago in the environment of Tibet.

Second, highly historians speculate whether these Tibetans actually attempted the sophisticated practice of selective breeding that is so popular today. Early Tibetans were hunters and farmers who depended on Tibetan dogs to hunt, protect herds and serve as stewards and fellow human beings. The natural tendency of the Tibetan breeds, formed by evolutionary forces, were more than enough for the tasks of ensuring the survival faced by Tibetans.

Third, the physical form of Lhasa Apso has largely maintained its original form since it is still able to keep warm when necessary. Cold-adapted animals have bodies with more muscle and fat ratio, compared bone mass with other races that have had to adapt to a warmer environment.

The heat produced by an animal is directly proportional to its weight or volume. The larger the body, the more heat it produces. What is known is that the heat loss is also proportional to the surface of the body, most surface There, you lose heat more rapidly. Keep the heat is a function of body mass in relation to the area, the majority of the surface lose heat more rapidly.

Because the body of a Lhasa Apso is shorter and rounder, which has less surface long legs, equal in weight, cousins warmer environment. These same forces also govern the type of body, people of Inuit ancestry have shorter bodies stronger and less surface mass equal weight Equatorial someone who has a long, thinner and a larger surface area. In short, to limit heat loss in cold, an animal is better served by a body that is so compact and short legs as possible.

Nature has adapted the body of a Lhasa Apso to adapt to the hills and peoples of the Himalayan highlands. This race is built for endurance, not speed, walking, jumping and climbing, and not as the bodies of other dog breeds.
