Stewart-Williams argues humans aren't distinguished by raw intelligence but by cumulative culture — the ability to stockpile knowledge across generations.

We stand on a pyramid of accumulated expertise inherited from prior generations, which is why a medieval peasant had technologies an Iron Age ancestor would need millennia to rediscover.
