New Caledonian crows afford invaluable comparative insights into human cumulative technological culture

Christian Rutz et al. Behav Brain Sci. .

Abstract

The New Caledonian crow may be the only non-primate species exhibiting cumulative technological culture. Its foraging tools show clear signs of diversification and progressive refinement, and it seems likely that at least some tool-related information is passed across generations via social learning. Here, we explain how these remarkable birds can help us uncover the basic biological processes driving technological progress.
