“…The considerable variation in European Acheulean assemblages through time and space, including variation in core reduction strategies, tool blank production, flake tool types and handaxe morphology (e.g. Ollé et al ., 2013; Moncel et al ., 2015; White, 2015; Hérisson et al ., 2016; Moncel and Ashton, 2018; White et al ., 2018; Davis and Ashton, 2019; Shipton and White, 2020), has been interpreted as representing the flexibility of Acheulean technological behaviour in adapting to local circumstances (Moncel et al ., 2015; Ravon, 2019), which may lead to the development of local traditions of production and manufacture (Ashton, 2018; Davis and Ashton, 2019; Ashton and Davis, submitted).…”
