Dogs’ evolution shows why they ‘love’ gnawing on bones

Scientists say they have discovered why dogs love to eat meat and bones.

Ancient canines adopted pack-living about eight million years ago, to hunt larger prey, according to researchers.

The resulting evolution of their jaws gradually turned the ancestors of modern wolves, and ultimately our own pets, into hypercarnivores.

Dr Joao Munoz-Doran presented the findings at the First Joint Congress for Evolutionary Biology in Ottawa, Canada. — via BBC News
