Researchers have assembled the most comprehensive map of dog breeds to date, using genetic sequences from 161 modern breeds. The largest evolutionary tree also reveals new information about the original purposes for breeding certain types of dogs; tells the story of the dogs that accompanied humans across the Bering land bridge; and the map could […]

Your dog can remember more than you think
Memory in non-human animals is largely a black box, because in humans the biggest proof of memory we have is transmitted through language. But new evidence suggests that dogs may also have memories of moments in a time and a place, known as episodic memories. This was demonstrated through a game where dogs were tested […]
Dogs evolved with climate change
The evolution of North American dogs shows that evolution can be a direct consequence of climate change, and is not always associated with an “arms race” between ancient dogs and their prey. Researchers studied fossil elbows and teeth of 32 species of dogs from 40 million years to two million years ago, the same period when climate […]
