Dogs explain early human success?

Well, the dog lovers among us will be pleased with this:

“Dogs help hunters find prey faster and more often, and dogs also can surround a large animal and hold it in place by growling and charging while hunters move in. Both of these effects would increase hunting success,” Shipman said. “Furthermore, large dogs like those identified by Germonpré either can help carry the prey home or, by guarding the carcass from other carnivores, can make it possible for the hunters to camp at the kill sites.” Shipman said that these predictions already have been confirmed by other analyses. In addition, she said, “if hunters working with dogs catch more prey, have a higher intake of protein and fat, and have a lower expenditure of energy, their reproductive rate is likely to rise.”

Another unusual feature of these large mammoth kill sites is the presence of extraordinary numbers of other predators, particularly wolves and foxes. “Both dogs and wolves are very alert to the presence of other related carnivores — the canids — and they defend their territories and food fiercely,” Shipman explained. “If humans were working and living with domesticated dogs or even semi-domesticated wolves at these archaeological sites, we would expect to find the new focus on killing the wild wolves that we see there.”

Of course, the dogs don’t “explain” human success. The ability to incorporate dogs into a hunting group is part of the story.

Cat lovers, keep watching this space. Your turn will come.
