There is a lack of connection between the cognitive neuroscience and evolutionary approaches to the study of the mind, in philosophy as well as the sciences.

Neuroscience research calls into question her assumption that substance concepts play a role in practical skills and suggests that (...) conceptual knowledge in the brain may be organized by perceptual features rather than by individuals and natural kinds.
