Uncontroversial evidence of vocal production learning, the capacity to modify vocal output on the basis of experience, is sparsely distributed in the animal kingdom. We suggest that this is in large part due to a trade-off between vocal learning complexity and a much more widely distributed trait—non-vocal dexterity. We argue that given some generally required neural and anatomical conditions for [...]

Executive functions are a set of cognitive control processes required for optimizing goal- directed behaviour. Despite more than two centuries of research on executive functions, both in humans and nonhuman animal species, there is still a knowledge gap of what constitutes the mechanistic basis of evolutionary variation in executive function abilities. Here we show experimentally that changes in [...]
