Facial expressions are hereditary

Facial expressions are hereditary

A study by Israeli scientists shows that people’s facial expressions are hereditary. Through the study of blind subjects (they can’t  imitate their parents)by the researchers at university of Haifa, Israel, they have found that there are great similarities in the facial expressions between the members of a family, but compared with positive expression, negative expression is more likely to be inherited. Scientists have first proved that facial expressions are mostly originated from gene rather than imitate others.
