Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

What Do Lithics Tell Us About Cultural Evolution? Insights From the Central African Record
ABSTRACT While Western historical narratives often incorporate a biased vision of human evolution—driven by a progressive view tied to a progressively evolving state of culture—this paper proposes combining archaeological lithic data with epistemological reflections to critique the modern regime of historicity, where progress is assumed as rational ...

Digital Transformation of Retail Work: The Rise of Chaotic Rationalisation
ABSTRACT We examine how new digital technologies are transforming labour processes in frontline jobs in United States (US) store‐based retail, examining the US as an extreme case of labour market liberalisation. Research on technological change presents three scenarios: job displacement, job enrichment and ‘digital Taylorism’ involving heightened ...

ABSTRACT Sociolinguistic research has long documented the appropriation of African American Vernacular English (AAVE) across media including film, music and advertising. In this article, we add to this body of work by exploring the digital recontextualisation of a subset of AAVE features as ‘TikTok/internet language’.
