If i had no language would i have no thoughts?

What is the evolution of language? We have a genetic capacity for language, but which came first? If we evoloved language prior to our capacity, then why our we unique? if our capacity came first, then what was its orginal purpose?The abstract mind creaates a simulation of reality interanally. IT is this that we call consiuosness. Yet this simulation was created solely and compleatly by langouage. Robbed of all language, we are reduced to mere emotion driven animals. What did we think about prior to langauge or could we think at all? Was the creation of a language, as a genetic tool for communal hunting/survival, create an accidental path ot consiousness.
