Adaptive specialisations:
Helped the development of social interactions in primates
Include the over representation of the fingers and lips of the human sensory motor cortex
Represent a disproportionately large area of cortex relative to the rest of the body surface
Could explain behavioural differences between closely related species
All of the above
