For several decades, it was largely assumed that stone tool use and production were
abilities limited to the genus Homo. However, growing palaeontological and archaeological …

The discovery of the earliest known stone tools at Lomekwi 3 (LOM3) from West Turkana,
Kenya, dated to 3.3 Ma, raises new questions about the mode and tempo of key adaptations …

ABSTRACT The Slit–Robo GTPase-activating proteins (srGAPs) were first identified as
potential Slit–Robo effectors that influence growth cone guidance. Given their N-terminal F …

Modern humans are characterized by specialized hand morphology that is associated with
advanced manipulative skills. Thus, there is important debate in paleoanthropology about …

The visuospatial system integrates inner and outer functional processes, organizing spatial,
temporal, and social interactions between the brain, body, and environment. These …

Trabecular bone remodels during life in response to loading and thus should, at least in part,
reflect potential variation in the magnitude, frequency and direction of joint loading across …

Hand bone morphology is regularly used to link particular hominin species with behaviors
relevant to cognitive/technological progress. Debates about the functional significance of …

Abstract Objectives Humans display an 85–95% cross‐cultural right‐hand bias in skilled
tasks, which is considered a derived behavior because such a high frequency is not …

Objectives The dexterity of fossil hominins is often inferred by assessing the comparative
manual anatomy and behaviors of extant hominids, with a focus on the thumb. The aim of …

Systematic tool use is a central component of the human niche. However, the timing and
mode of its evolution remain poorly understood. A newly developed method for the analysis …
