Abstract

Movement tracking using the deep-learning network DeepLabCut has revealed how a species not known for tool use acquires and refines tool skills. This opens the door to detailed cross-species comparisons of the behavioural, cognitive, neural and evolutionary processes that turn naïve actions into expertise.
