title: Teaching as an exaptation.
abstract: We appreciate and endorse Kline's ethological taxonomy and its application. However, the definition of teaching she presents is problematic, as it replaces mentalistic intent with intention on the part of natural selection. We discuss problems with the strict adaptationist view and suggest instead that the five forms of teaching presented in the taxonomy may constitute exaptations rather than adaptations.
