Although dogs look sad, why can’t wolves from the same family show such expressions? When you find out the reason behind it, you will say “Wow!” You will say!

“Evolution of facial muscle anatomy in dogs” A current article entitled (Evolution of facial muscle anatomy in dogs) facial expressions of dogs He came to an important conclusion regarding the

Research shows that during the domestication process of dogs changes in the facial muscles By investigating this, it aims to reveal what role these changes play in communicating with people.

So what kind of methodology does this research have?

In the context of the research, 27 domestic dogs and 9 wild wolves The anatomy of the facial muscles is examined relatively.

Especially the facial expressions these species display during social interactions movement of the inner eyebrow upwardsis observed and the frequency and intensity of this movement are recorded.

What do the research results show? The facial muscles of dogs and wolves are anatomically different!

The anatomy of the facial muscles between wolves and dogs is only in the muscles around the eyes It turns out that there are significant differences.

In this regard, although in dogs there is a muscle that provides the internal movement of the eyebrows, in wolves this muscle is absent or is represented only by a small tendon, that is, it is as small as in dogs. is not functional is being observed.

Researchers say this anatomical difference allows dogs to raise their eyebrows more clearly more pronounced facial expressions He argues that it allows them to exhibit.

This muscle, which wolves lack, allows domestic dogs to communicate with humans!

Dogs perform the inner eyebrow movement much more often and with a higher intensity than wolves move to communicate It is said to be so.

Researchers have found that these facial expressions allow dogs to communicate more effectively with humans, and that this communication helps people become more resistant to dogs. more relevant says it makes it happen.

According to researchers, these facial expressions, made with the eyebrows of dogs that have been domesticated and whose needs are recognized by humans, make people more interested in the dog, making it more likely that dogs will become more interested in dogs. to survive and can increase the chances of re-appropriation.

Taken together, these findings indicate that dogs were shaped by human behavior during the domestication process. anatomical and behavioral changes It yields an astonishing amount.

As with any research article, this study also applies There may be some restrictions Let us conclude our content by stating that it would be appropriate to generalize it within the scope of its own example.
