This National Science Foundation (NSF) Project Grant, under the Social, Behavioral, and Economic Sciences program (CFDA 47.075), awards $317,985 to George Washington University to develop new methodologies for identifying evidence of organic (wooden) tool use in early human ancestors. The key products and services to be delivered under this 3-year project include:

  1. Collecting, documenting, and analyzing organic tools used by non-human primates to establish a catalogue of natural and artificial damage patterns on wood.
  2. Conducting controlled experiments with a percussive robot to investigate how variables like species, moisture content, etc. impact the formation of percussive traces on wood.
  3. Applying machine learning models to distinguish between natural and tool-use induced damage patterns in the wood samples.
  4. Analyzing fossilized wood specimens dated 4-2 million years old to identify evidence of percussive organic tool use by early human ancestors.

The overarching goals are to develop methods for identifying organic tool use evidence and establish whether such tool use existed in early human ancestors. This research aims to provide new insights into the origins of human technology and behavior. No sub-awards are planned for this project.
