Which statement describes the relationship between humans ability to identify animal grimaces sound deciphering other facial expressions

yeah

Explanation:

Scientists are starting to be able to accurately read animal facial expressions and understand what they communicate.

Facial expressions project our internal emotions to the outside world. Reading other people’s faces comes naturally and automatically to most of us. Without your best friend saying a word, you know—by seeing the little wrinkles around her eyes, her rounded, raised cheeks and upturned lip corners—that she got that promotion she wanted.

What if we could just as easily read the faces of other living beings? Will there come a day when we can hold up a smart phone to our cat and know how he’s feeling?

Researchers are developing coding systems that enable them to objectively read animal facial expressions rather than inferring or guessing at their meaning. A coding system precisely describes how different facial features change when an animal feels a particular emotion, such as squinting an eye or pursing lips. By looking at photographs and scoring how much each of these features or “action units” change, we can determine how strongly an emotion is felt.

Pain recognition first frontier

So far, only pain coding systems (grimace scales) for non-primate animals have been scientifically developed. Despite their different anatomy; mice, rats, rabbits, horses and sheep (including lambs) all pull a similar pain-face. They tighten their eyes, bulge or flatten their cheeks, change the position of their ears and tense their mouths.

Lambs are one of the animals that have been shown to grimace when in pain.

The push to develop grimace scales has largely come from our desire and ethical duty to assess and improve the welfare of animals used in labs or for food products.

Ideally, we want a way to accurately and reliably know how an animal is feeling by simply looking at them, rather than by drawing blood for tests or monitoring heart rates. By knowing their emotional states, we can change help to reduce pain, boredom or fear and, ideally, foster curiosity or joy.

Animals, particularly social ones, may have evolved facial expressions for the same reason we did—to communicate with one another, or, in the case of dogs, with us.

Particularly for prey animals, subtle cues that other members of their group (but not predators) can pick up on are useful for safety, for example. A pain behavior cue may trigger help or comfort from other group members, or serve as a warning to stay away from the source of pain.

If we can decipher grimacing, we should also, theoretically, be able to understand facial expressions for other emotions such as joy or sadness. We would also likely want to comprehend facial expressions for the animals closest to our hearts: our pets.
