If evolution of a man took place in different regions the world the  communication adopted the shape of dialects and languages. Hunders of dialetcs or dozens of languages can be found in India . Europe also  has so many different languages. All human species smile and weep in the same language.
However the language which a women  uses for communication  is most difficult to understand as man has been trying to understand what a women wanted to say and what she has really said and what she could have said . Language of silence is still the most common language practiced on this earth. How to understand what one wants to say but is not saying . Tounge is not the only means of communication. Perhaps eyes could be another. I dont know if eyes communicate more which words cant .
More and more we talk on mobile phones more and more we become silent and dont let our inner feelings come out .
Is this  sign of evolution.
