Summary

Researchers developed a new method to determine human handedness in ancient populations using stone tools. This technique, analyzing the cone of percussion on lithic flakes, offers a complementary approach to existing methods for studying early human behavior.

Area of Science:

  • Paleoanthropology
  • Archaeology
  • Human Evolution

Background:

  • Inferring human handedness in pre-modern populations has been challenging due to a lack of reliable methods.
  • Existing techniques, like Toth's cortex method for lithic flakes, show promise but have limitations in applicability and signal-to-noise ratio.

Purpose of the Study:

  • To introduce and evaluate a novel method for inferring human handedness from lithic evidence.
  • To present an alternative technique that complements existing approaches.

Main Methods:

  • The study focuses on analyzing the orientation of the cone of percussion in lithic flakes.
  • This method is based on the physical evidence left by tool manufacture.

Main Results:

Related Experiment Videos

  • Preliminary experimental data suggest that the cone of percussion method can reliably infer handedness from lithic artifacts.
  • This new method shows potential as a complementary tool to the cortex method.

Conclusions:

  • The cone of percussion method offers a viable new approach for studying human handedness in the archaeological record.
  • Further research is recommended to validate and refine this technique for broader application in paleoanthropological studies.
