That's funny, but if your serious then your response does not make much sense here. My point is: Language came early in human development and to humans everywhere, without exception. Indeed the need to communicate may have been one of the main selectors justifying the cost (Brains are expensive to run). But many tribes are ok without maths and it has been around for just about three millennia and so could not possibly have had much influence on brain development.
