Speaking of which, friends who love dogs
The most irresistible
It's their innocent, big eyes.
Being gazed at by them with such tender affection
Who could withstand that?
but
Do you think dogs are born with those innocent, big eyes?
wrong!
A study published in the Proceedings of the National Academy of Sciences of the United States of America shows that:
A dog's innocent eyes are meant to please humans.
It evolved!
Everyone knows
Dogs' ancestors were wolves.
Wolves don't have innocent eyes.
But the research team stated
After dissecting the bodies of four wolves and six dogs, they discovered...
Dogs have two more muscles around their eyes than wolves.
It can easily raise the inner brow.
In addition, they also recorded the expressions of 27 dogs and 9 wolves.
When they were found staring at humans
Dogs often pull their eyebrows back.
Make a nervous or sad expression.
However, wolves do not exhibit such an expression.
As for why the dog did this
Experts say
That's because of the two special muscles around a dog's eyes.
It emerged over thousands of years of evolution!
Speaking of this, I have to say
Dogs are really smart
They discovered that it mimics the appearance of a baby with innocent eyes.
It can evoke human compassion
People who like making this expression
A higher survival rate can be achieved.
So over time
They possess such abilities.
However, experts emphasized
There is one breed of dog that doesn't have innocent eyes.
That's... a husky!
Experts speculate
Because humans originally domesticated them for pulling sleds.
Become a partner in work
Pets that are not close to humans
So huskies don't care about this ability...
In other words
All dogs have a muscle around their eyes.
Able to enlarge the eyes towards the ears through the eyelids
Besides the husky
Now you understand, right?
It's not that the husky made a mistake and destroyed the house but refused to admit it.
They genuinely don't know how!
