Experimental Insights into the Cognitive Significance of Early Stone Tools
Stone-flaking technology is the most enduring evidence for the evolving cognitive abilities of our early ancestors. Flake-making was mastered by African hominins ~3.3 ma, followed by the appearance of handaxes ~1.75 ma and complex stone reduction strategies by ~1.6 ma. Handaxes are stones flaked on two opposed faces ('bifacially'), creating a robust, sharp-edged tool, and complex reduction stra...
متن کاملNotes on Early Acheulian Stone Tools: Constitutive Operations and Analogies of the Soul
Early Acheulian bifaces appear to be characterized by seven basic operations. After a brief description of each operation, I propose how the pattern of that operation had the capacity to serve as an analogue for a concept of the soul that could be expressed both in self-concept (selfobject) and interpersonal relations (object relations). 1. A 'core' is flaked and the flake is trimmed, in turn, ...
متن کاملDefining and measuring reduction in unifacial stone tools
Observations pertaining to particular stages of the lithic chaı̂ne opératoire, or reconstructions of the entire operational sequence at a particular site, can be used to develop a detailed understanding of past human cognitive capabilities, technological sophistication, mobility, and land use. The ‘‘reduction sequence’’ is a specific stage of the chaı̂ne opératoire that many archaeologists have a...
متن کاملInterisland and interarchipelago transfer of stone tools in prehistoric Polynesia.
Tracing interisland and interarchipelago movements of people and artifacts in prehistoric Polynesia has posed a challenge to archaeologists due to the lack of pottery and obsidian, two materials most readily used in studies of prehistoric trade or exchange. Here we report the application of nondestructive energy-dispersive x-ray fluorescence (EDXRF) analysis to the sourcing of Polynesian artifa...
متن کاملStone tools, language and the brain in human evolution.
Long-standing speculations and more recent hypotheses propose a variety of possible evolutionary connections between language, gesture and tool use. These arguments have received important new support from neuroscientific research on praxis, observational action understanding and vocal language demonstrating substantial functional/anatomical overlap between these behaviours. However, valid reas...
