The only successful attempt: humanity has tried to domesticate wolves several times, and modern dogs are the only successful result

From ITCommunity:

For thousands of years, the line between wolves and dogs has been blurred. Groups of people in different parts of the world, independently of each other, have repeatedly tried to domesticate wild wolves. However, we can see the result of only one such attempt today. A recent study shows that even after dogs spread across Eurasia and the Americas, people in what is now Alaska interacted with a strange mix of dogs, wolves, wolf-dog hybrids, and some coyotes.

Archaeologist François Lano from the University of Arizona and his colleagues studied 111 sets of dog and wolf bones from archaeological sites in the interior of Alaska.
