why the baby's first word was mama and papa?

Most babies say the word 'Mama' and 'Papa' as their first utterance. You know why? Some scientists try to explain the scientific explanation ..
Clearly, Mom and Dad are the ones who have always been around babies, so little attention focused on them. Well, it turns out, a variety of languages ​​around the world simplify the process of getting this pronunciation for the baby, to make a call to my father and mother using a repeated pattern of sounds.
Mama…
Dada…
Papa…
Baba…

This is just some examples.
  
Brain Research in Newborns

To arrive at this conclusion, brain research has been carried out on 22 newborns aged 2-3 days. While their brains were observed, the researchers running the recording of words without meaning to these babies. This recording contains words that sound repetitive and also the words that are not repeated. Everything is meaningless.


Apparently, the baby's left front brain activity looks increases each time recording the repeated words  (repetitive) is played. In contrast, no repeated words showed no signs of baby's brain response.


conclusion
In adults who are right-handed, the center of language skills are at the left brain. This is consistent with the results of research on infants and reinforce the theory that humans are born with the ability to learn their  native language systematically and efficiently.
