| What you saying is one side of speculation/explanation. The article particularly mentions that when babies are in the womb, they feel content and that's what the smiling is, but we don't know if it is for sure. (i.e. it can be just a reflex, or actual display of being "content"). Smiling, however, cannot be interpreted as preparation for birth but may be a reflex, Prof Campbell said. He added: "What's behind the smile, of course, I can't say, but the corners turn up and the cheeks bulge ... I think it must be some indication of contentment in a stress-free environment." in any way, so socialization is a big part of it. We know most humans are born with the ability of speech, but if they are not taught/socialized at early age, then they will never be able to speak later (apart from uttering primitive sounds), but they still can utter sounds. It could be the same with smiling. All humans are born with the ability of a 'primitive smile' which can be further developed and refined socially, but ability is innate. The studies that mention that all smiling is socialized is yet another wave of bunk science that tries to attribute "socializing" and indoctrination to every human behavior, where there are clear indication that it is not true. http://www.doctortipster.com/6920-smiling-is-an-inherited-be... |
