A study of chimpanzees'
use of hammers to open
nuts in western Africa
may provide fresh clues
to how tools developed
among human
ancestors. A paper
published in the May 24
issue of the journal
Science documents the
first archaeological examination of a non-human primate workplace
and establishes new links between the use of tools by chimpanzees
and similar developments among human ancestors (hominids). The
research was supported in part by the National Science Foundation
(NSF).
