The math gene: How mathematical thinking evolved and why numbers are like gossip

This work about maths and language is from the NPR commentator Keith Devlin. Why is maths so hard? And why, despite this difficulty, are some people so good at it? If there is some inborn capacity for mathematical thinking which there must be, otherwise no one could do it, why can't we all do it well? Keith Devlin has answers to all these difficult questions, and in giving them shows us how mathematical ability evolved, why it's a part of language ability, and how we can make better use of this innate talent. He also offers a theory of language development - that language evolved in two stages, and its main purpose was not communication. Devlin goes on to show that the ability to think mathematically arose out of the same symbol-manipulating ability that was so crucial to the emergence of true language. Why, then, can't we do maths as well as we can speak? The answer, says Devlin, is that we can and do, we just don't recognize when we're using mathematical reasoning.
