The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

Biological Reviews, EarlyView.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated
