The homosapiens main skill was starting fires it was there key skill because it was there source to survival not only did it keep them warm it was good for cooking food.
The people’s strengths were there ability to communicate with others. With the homosapiens learning how to talk to others this helped them with the survival process. And this is what lead them to start talking about 2 million years ago.
Homosapiens weren’t able to talk for a very long time before they were able to talk they used symbols and hand gestures as a method of communication.
Ever since homosapiens are able to live and survive on our own and to talk on our own for a number of years people’s language has changed there clothes have changed and survival methods have changed.
