 These phenomena are recognised by many prominent theorists of cultural evolution. Laland et al. stress this theme in their work on niche-construction—i.e. the role of organisms in fashioning their environments—when they remark that, ‘We inherit a world of our making...This is both our ecological and our cultural inheritance’ (2001). Sterelny’s work on the evolution of cognition (e.g. Sterelny 2012) also places stress on what he sometimes calls ‘scaffolded learning’. Like Hobaiter et al’s chimps, unskilled, ignorant or uninitiated human novices can find their epistemic burdens greatly eased by the ways in which the environments in which they learn are littered with the fruits of past activities of adepts.
