Abstract
The concept of ‘mutation’ is a central one in the interaction of genetics and evolution theory, and is included in most school biology courses. However, when secondary students in Barcelona were asked about the concept some treated the term as synonymous with metamorphosis, or with other developmental changes. Some of these interpretations may be due to linguistic features of Catalan, the language of the school, but the data suggest that it is not valid to assume that introducing the term in the context of genetic changes is sufficient to ensure that the pupils restrict the meaning to that context.
