It has long been known that of all animals, only dogs demonstrate an unprecedented level of love and affection for humans.
However, not everyone knows how we “earned” such a warm attitude from our pets.
Experts note that dogs can be called, perhaps, the smartest animals in matters of social interaction with humans.
Dogs do not have a brain as large as an elephant or a bear, but they have an actively developed cortex.
Few people know that dogs can boast of having GTF21 and GTF21RD1. Thanks to these genes, dogs demonstrate a desire to communicate with people, trust, love and affection.
Some people may also have these genes. They will be associated with a certain form of mental retardation. However, patients tend to be trusting and docile.
Despite the fact that these reasons largely explain the warm relationship between humans and dogs, this issue is still being discussed by the scientific community.
