NY Times article on the origin of language

HERE.

The topic is new research that posits a single origin for human language, in the southern part of Africa.

One especially interesting point here: just as human genetic diversity decreases the further you move away from Africa, the same is true of phomenic diversity. Some of the African click languages use 100 phonemes. English uses 45. Hawaiian (about as far from Africa as you can go, genetically) uses only 14.
