Collard, Mark	2011	The relationship between population size and toolkit diversity and complexity will be greater among food-producing (i.e. pastoralist, horticulturalist, and agriculturalist) groups than among hunter-gatherers, whereas relationship between risk of resource failure and toolkit diversity and complexity will be greater among hunter-gatherers than among food-producers (253).
