What can lithics tell us about hominin technology's ‘primordial soup’? An origin of stone knapping via the emulation of Mother Nature

Archaeometry, Volume 68, Issue S3, Page S8-S30, June 2026.
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)

Anuran Assemblage Structure in the Serra Da Capivara National Park, Piauí State, North‐Eastern Brazil

Austral Ecology, Volume 51, Issue 4, April 2026.
ABSTRACT Biological communities consist of species that coexist and interact with each other and the environment over the same spatial and temporal scales. How species use the available resources can shape community structure, particularly in mechanisms that favour species coexistence, such as niche partitioning. This study investigated the spatial and
