The origins of the ancestors of human speech to be found in the specific language of the mothers in the world talk to their babies. Such a conclusion was an anthropologist at Florida State University Professor Dean Falk.
According to the professor, the child's speech is formed according to the same principles as the speech of primitive man. How is the child's speech? In Year 1 child uses already 3-4 "bubbling words," understand the individual words, relates them to specific objects.
Formation of speech is related to two other milestones in the evolution of man — bipedal locomotion and an increase in brain volume. If so, the appearance of first significant relates to an earlier period of evolution — 1.6 million years ago. Until now, scientists thought that human ancestors acquired the ability to speak only 100,000 years ago.
As explained by Professor Falk, when man began to move around on two legs, and the hair on his body was much smaller babies could no longer cling to their mothers. Now, while the mother gets food, she had to leave the baby alone. And so he did not cry, the mother was making special soothing sounds. Thus, according to the professor, was born language.
As you know, in the course of natural selection, survival of the fittest. Moms who "talk" with their children better able to collect more food, which means that they were more likely to survive and pass on useful quality offspring.
On the "mother" language are able to speak and modern mom. They speak in a high voice, pulling vowels and many times repeated the word. In response, the children have to begin to talk a little.
