title: Modeling the evolution of the cerebellum: from macroevolution to function.
abstract: The purpose of this contribution is to explore how macroevolutionary studies of the cerebellum can contribute to theories on cerebellar function and connectivity. New approaches in modeling the evolution of biological traits have provided new insights in the evolutionary pathways that underlie cerebellar evolution. These approaches reveal patterns of coordinated size changes among brain structures across evolutionary time, demonstrate how particular lineages/species stand out, and what the rate and timing of neuroanatomical changes were in evolutionary history. Using these approaches, recent studies demonstrated that changes in the relative size of the posterior cerebellar cortex and associated cortical areas indicate taxonomic differences in great apes and humans. Considering comparative differences in behavioral capacity, macroevolutionary results are discussed in the context of theories on cerebellar function and learning.
