The article stated under the Biology section: "The number of natural, pure-bred bred dogs declines over time as dogs naturally crossbreed; a short period of time is suggested by the fact that there are over 100 different natural, pure breeds of dog thriving today." The statement asserts that the number of pure dog breeds is diminishing, suggesting that if we extrapolate backward in time, an old-Earth would be overrun with pure breed dogs. Dogs, however, were domesticated only a few thousand years ago by man from more docile wolves, and even then only a few pure breed dogs existed for centuries. Only in the 19th century did the number of dog breads exploded in the western world as designer dogs because a status symbol amongst the newly emerging middle class and new uses for dogs were discovered. The argument directly states that the number of pure dog breeds is diminishing due to crossbreeding - while the genetic purity of older dog breeds is slowly being diluted, new designer dog breeds are always being developed (as tradition stretching back over a century). | The article stated under the Biology section: "The number of natural, pure-bred bred dogs declines over time as dogs naturally crossbreed; a short period of time is suggested by the fact that there are over 100 different natural, pure breeds of dog thriving today."
