Reddit mentions of How Monkeys See the World: Inside the Mind of Another Species

I did my master's degree thesis on this when I graduated from university -specifically, my topic was "The evolution of language in homo sapiens". Most of what I posting here is from research papers that I read at the time; but I also read a lot of books on the topic. I highly recommend Kanzi: The Ape at the Brink of the Human Mind for information about Kanzi, How Monkeys see the World for information about vervet monkeys, and Steven Pinker's excellent book The Language Instinct for an overview of some of the best science dealing with human language. I basically agree with Pinker's view (and indicentally, the view that ecaward posted a little higher) that primates and some other animals are capable of communicating with symbols; but that the real power of language lies in our ability to recombine symbols through syntax and so alter the meaning, and this escapes primates: it's a uniquely human evolutionary adaptation.
