Conteúdo: | The Norway rat may be considered to be the first animal to have become domesticated for strictly scientific purposes. It offers excellent opportunities for studying the anatomical, physiological and behavioral changes of domestication for the following reasons: 1) The live wild Norway rat is readily available in large numbers throughout the world in cities, towns, and on farms, and equally large numbers of domesticated Norways rats are available in scientific laboratories throughout the world. 2) Since the domesticated Norway rat has been used in almost every field of biological research, more is known about it than any other animal, with the possible exception of man. 3) Wild and domesticated Norways rats breed with one another. Neither breeds, as far as is known, with any other rat - not even the Alexandrine or roof rat, which next to the Norway is the most common rat in the world. The fact that the Norway and Alexandrine rats do not breed is extraordinary in view of their great similarity in appearance, only the initiated being able to tell them apart. 4) The short life span of this rat, and early age of maturity make it possible to follow the inheritance of various characteristics throughout many generations withion a few years' time. 5) The Norway rat is very similar to man in many ways, particularly in dietary needs, geographic distribution, world population and colony formation.
