Attached to: Language May Have Evolved Earlier Than Supposed
Language probably developed gradually over tens of thousands of years. The first words were probably danger warnings, then maybe things related to day to day survival such as words for various foodstuffs. I would not be surprised to find out that Homo Erectus had rudimentary language. Even today various animals have calls that correspond to danger signs, and primates such as chimps seem to be able to communicate fairly well without what we would call acutal language. Communication predates humanity, so it's only natural that apes with big brains (us) would take it to the next level and begin to transmit abstract information using vocalizations.
