“It was, after all, much less work to go beachcombing than to rely on catching deer, elk and aurochs, which might escape the hunter for days at a time, a change ‘away from the high-risk, high-yield, high-energy expenditure strategy of game hunting to a low-risk, moderate-yield, low-energy expenditure strategy’, in the concise words of Barry Cunliffe.16 One could go further: the dependence of these folk on the produce of the sea must have affected their system of values, which would place less emphasis on the martial skills associated with hunting (casting spears, shooting arrows, and so on) and more on the nautical skills needed to master even inshore waters.”
