and how 10,000-year-old chewing gum may change our understanding of ancient society.

Let's satisfy some curiosity.

Dogs are supposedly man's best friend, and new research suggests at least one reason why our

puppy pals goes so well with humans. It turns out that dogs are so hyper devoted to us

that it seems they have evolved a special region in their brain for processing

human faces. Humans domesticated dogs thousands of years ago, so we've been

companions for a long time.

We've basically evolved to love each other and that love runs deep.

Dogs understand us better than monkeys do,

even though genetically monkeys are our close relatives.

Dogs recognize our faces, read our facial expressions, and even take on our moods.

So if you think it makes your dog sad when you cry, you're right.

Researchers wondered if this connection with humans show up in a dog's neural pathways.

So a new study focused specifically on how dogs recognize faces.

The hope was to figure out whether there's a region in their brain for processing human faces,

and if there is, was it a different area from one that processed dog faces?

To explore this, they used fMRI brain scans on a dozen dogs, all trains to hold still
