Why we can’t have a unifying base Language For Mankind ?
Researchers claim that our first sign were primitive gestures and sounds developed much later. Around 50,000 years ago humans were supposed to have developed the behavioral modernity .That modernity laid the foundation stone for the evolution of language. Currently it is estimated that around 6000 to 7000 languages are spoken in the world. The first thing that anyone discovers while learning a foreign language is the diversity as the primary characteristics of human language. A language can never evolve if the contact between people to person is more than enough to communicate. There can’t be a unifying base language for humans as some sentence structures have no basis at all in some culture, so automatically the concept of universal grammar dies.
