Moms all over the world often fed and lull their children is on the left hand with an ulterior motive, and not by chance. This habit lurk serious evolutionary reasons. What namely, the researchers found, and the sitekolobok.ua.
When a baby looks at her mother's left eye, his right brain active, which is responsible for the formation of attachment between mother and child, as well as for the development of social skills. This fact has been described in detail in the scientific work "Lateralization mother-calf interaction in various mammalian species"Published in the edition of Nature.
"Brain Asymmetry and asymmetric position of the child about the mother (that is, seeing her one left eye) contributes to the active development of social skills. - stated in the study. - For example, children 5-11 years checked on which side they prefer to bypass the teacher. It turned out that on the right. Because most of the time they want to keep it in sight of the left eye. "
Within five years, scientists from several countries studied the brain asymmetry, watching for females and cubs of wild horses, walruses, reindeer, musk oxen, saiga antelope, kangaroo, killer whales, belugas and whales. And according to the results became evident, the animals as well as people try to keep their babies on the left, inheriting the asymmetry of the brain from distant ancestors par with the saiga and whales.
Scientists have found that the behavioral habit young need not to lose sight of the mother and survive. TOhen mother is constantly in sight of a baby on the left, the image activates the right half of the brain and appear to contribute to the formation of play and social skills.
