Dear MEL Topic Readers,
Dogs’ eyes evolve to appeal to humans
You know it.
Dogs often make an attention-grabbing expression or noise when they want their owner to do something for them, such as petting and feeding. You may take it for granted, but researchers found that such infant-like expression is a result of evolution over millenniums.
Since domesticated dogs no longer need to develop strong jaw muscles to bite other animals or tear the meat off the bone, they seem to have developed a muscle to raise the inner eyebrow over time instead to make a non-verbal appeal to humans, just like human infants do. Indeed, they seem to have learned such subtle and delicate, yet effective communication means to get along with, or even take advantage of human feeling.
Are they getting smarter than our cousins in the wild, apes or monkeys, that share the same ancestor? Maybe, at least when it comes to living with humans.
Over the next few millenniums, humans may be trained to do what dogs’ eyes tell them to do.
Enjoy reading the article and look at dogs’ eyes carefully when they demand something.
