How did man first begin to use language?

Intuitively, one might speculate that hominids (human ancestors) started by grunting or hooting or crying out, and 'gradually' this 'somehow' developed into the sort of language we have today. (Such speculations were so rampant 150 years ago that in 1866 the French Academy banned papers on the origins of language!)

Can language help modern humans learn?

Rather than considering toolmaking as a proxy for language ability, he and his colleagues explored the way that language may help modern humans learn to make such tools. The researchers recruited 184 students from the University of St. Andrews in the United Kingdom, where some members of the team were based, and organized them into five groups.

How does language change over time?

As far back as we have written records of human language - 5000 years or so - things look basically the same. Languages change gradually over time, sometimes due to changes in culture and fashion, sometimes in response to contact with other languages. But the basic architecture and expressive power of language stays the same.
