    'Puppy dog eyes'

    Ever wondered how dogs learned to use their "puppy eyes" to bend us to their will?
    It turns out our pet pooches have evolved human-like eyebrow muscles, which let them make the sad faces that melt our hearts, according to a new study published on Monday in the Proceedings of the National Academy of Sciences (PNAS).
    It involved dissecting the cadavers of domestic dogs and comparing them to those of wild wolves, our best friends' ancestors, whom they branched off from around 33,000 years ago (don't worry, no animals were killed for the research).
    A separate part of the study saw scientists videotaping two-minute interactions between dogs and a human stranger, then repeating the experiment with wolves, to closely track how much they used a specific muscle around the eye that produced an inner eyebrow raise.
    The researchers found two muscles around the eye were routinely present and well formed in the domestic dogs, but not the wolves, and only dogs produced high-intensity eyebrow movements as they gazed at the human.
    "It makes the eye look larger, which is similar to human infants," Professor Anne Burrows of Duquesne University in Pittsburgh, who was one of the co-authors, told AFP. "It triggers a nurturing response in people."
    Since the muscles were robust in the dogs but not wolves, "that tells us that that muscle and its function are selected," she added.
    The current study was led by Juliane Kaminski at the University of Portsmouth and also included researchers from Howard University in Washington and North Carolina State University.
    It builds on past work, including a notable 2015 paper by a group of researchers in Japan that demonstrated that gaze exchange between humans and their pet dogs led to a mutual spike in the so-called love hormone oxytocin, similar to an effect seen between human mothers and their babies.
    But the latest work could explain how dogs are able to capture our attention in the first place.
    The paper also posits two other explanations for what is going on -- eyebrow movement may be significant for human-dog bonding "not just because it might elicit a caring response, but also because it might play a role during dog-human communicative interactions."
    Humans tend to pay attention to the upper facial areas of fellow humans during communication, and the dogs could be responding to this dynamic.
    A final hypothesis is that exaggerated eyebrow movements expose the white sclera of the dogs' eyes, which humans also have and find appealing in other animals (other primates have darkened sclera to camouflage their gaze).
    - Ancient breeds vs toy dogs -
    Intriguingly, a Siberian Husky that was dissected did not possess one of the two muscles that were present in other dog breeds, which pulls the corner of the eyelid toward the ears.
    That may be because Huskies are an ancient dog breed, and the best living representative of what the link between dogs and wolves may have looked like.
    Burrows said the main limitation of the study was the small number of cadavers -- four wild wolves and six domestic dogs -- and that this is a potential avenue for future study.
    "We're also going to drill down into that interesting variation we saw in the Husky," she said. "So we would like to take a look at additional ancient breeds like the Malamute, the Samoyed, and compare that to the toy companion breeds like the Chihuahua and the Yorkie."
    The work could also be extended to other animals humans have maintained close contact with, including horses, who appear to produce a similar movement, and cats.

    They already are.
    Liberty is lost through complacency and a subservient mindset. When we accept or even welcome automobile checkpoints, random searches, mandatory identification cards, and paramilitary police in our streets, we have lost a vital part of our American heritage. America was born of protest, revolution, and mistrust of government. Subservient societies neither maintain nor deserve freedom for long.

    Merlin, aka Emrys, owned me the moment he looked up at me in the back yard that cold October afternoon. A two week old, orphaned, desperate kitten pleading for help. That was over six years ago. I was rescued.

    TIL domesticated animals behave differently than wild animals
    A savage barbaric tribal society where thugs parade the streets and illegally assault and murder innocent civilians, yeah that is the alternative to having police. Oh wait, that is the police

    We cannot defend freedom abroad by deserting it at home.

    I didn't teach her squat. She be all like, "that's a nice piece of ham you are putting on your sandwich there; it'd be a shame if it fell on the floor" and damn if you don't drop it on accident.

    Lol my cats pretty much do the same thing but I never cater to their demands. If they want ham or turkey, they're gonna have to go to my brother or dad.

    Interesting...

    It does gives us both a two way street. We can better communicate with them, and they can better communicate with us. Most human / animal communication problems come from humans, not animals. We just dont know how to listen. Or maybe we have been too distracted to bother listening to what they have to say. Ive seen nothing build up a dogs self esteem and self confidence more than the dog knowing there are those of us who DO listen and DO pay attention to both wants and needs. One pleasing thing about these eye muscles is that I know damn good and well when they are smiling.
