Researchers have located a genetic mutation associated with smaller dogs.

Mutation That Gave Us Tiny Dogs Found in Ancient Wolves

The genetic factor that plays a large role in determining canine body size was around thousands of years prior to domestication

After comparing all genomes, the researchers found that the Japanese wolf is part of an evolutionary branch of wolves that arose 20,000 to 40,000 years ago. Some of the wolves from this branch evolved into the Japanese wolves while others branched off and gave rise to modern dogs.

Ancient Japanese Wolves May Be the Closest Wild Relative of Modern Dogs

The results challenge previous theories about the origin of dog domestication

The new gray wolf pups in Colorado have yet to be photographed, so for now you'll have to make do with this bright-eyed pair.

By Creating a 'Landscape of Fear,' Wolves Reduce Car Collisions With Deer

A new study in Wisconsin suggests the predators keep prey away from roads, reducing crashes by 24 percent

Supporters of the law argue wolves are a threat to livestock. However, only 102 sheep and cattle were killed by wolves last year. Idaho loses about 40,000 cattle to non-predator factors each year.

Dire Wolves Weren't Actually Wolves, DNA Analysis Reveals

Ancient DNA extracted from fossils shows the beast split off from Canis lupus and coyotes nearly 6 million years ago

There have been other ancient wolf remains found in places like Siberia, but finding a well-preserved specimen in Yukon is rare since the ground has to be permanently frozen and the animal must be buried quickly.
