Dog is man’s best friend. Where is it born? When did it evolve from wolves? What is the process and reason for this evolution? How did dogs migrate and develop on the earth? This is also A great mystery that rivals the pyramids in difficulty.
Before research using DNA technology, the generally accepted theory was that dogs split off from a certain group of canids, such as coyotes , hyenas , jackals and wolves, about 15,000 years ago. wait. However, the results of the first detailed DNA study shocked the academic community. Research has found that all dog species are descended from wolves, not other canids. The second part of the research was even more surprising: dogs "established themselves" about 40,000 to 150,000 years ago.
However, how did dogs originate from wolves? This is not difficult to answer, the answer is impossible. Some writers claim that primitive people in the Stone Age got along with wolves like friends and successfully bred the first "mutated wolf" - the ancestor of dogs. Don't believe this nonsense. The problem involves the critical stage when female and male wolves "jointly create" a new subspecies. Let's go back to the original question, what is a dog? A dog is a mutated wolf that only has the characteristics of its "wild parent". This answer is undoubtedly ridiculous. Therefore, the origin and evolution of dogs is another unsolved mystery.
