New Research Explains Why Dogs Aren’t Wolves

By Linda Cole

I admire the spirit of wolves, an animal who has found the world to be a hostile place, even though man has embraced a species that was born from them. There are similarities between dogs and wolves, but dogs are not wolves. The reason why is because of a makeup in their genome – the total genetic makeup of a cell.

After comparing D.N.A. from dogs and wolves, geneticists have determined that dogs are indeed related to the gray wolf. They studied the mitochondrial D.N.A. which remains unchanged as it’s passed down through the mother’s (maternal) line and found identical D.N.A. in both animals. Genetically, dogs and wolves are 98.8 percent identical.

Scientists are still debating when and how domestication of dogs took place and whether it was humans who first tamed wolves or if wolves found associating with humans in their best interest. Some scientists go so far as to say our early relationship with domesticated wolves was an important part in the development of the human species. The working relationship between wolf and man enabled humans to bring down bigger game which provided them with more food. More food led to larger families and a growth in human population. Wolves joined with man for a mutual relationship that benefited both sides.
