He is remembered for his theory of emergent evolution, and for the experimental approach to animal psychology now known as Morgan's canon, a specialised form of Occam's razor which played a role in behaviourism, insisting that higher mental faculties should only be considered as explanations if lower faculties could not explain a behaviour.
