- In biology, an atavism is a modification of a biological structure whereby an ancestral genetic trait reappears after having been lost through evolutionary change in previous generations.
- An atavism is a genetic trait that reoccurs after skipping several generations. If a person has blue eyes like her great great grandmother but her mother, grandmother, and great grandmother have brown eyes, then having blue eyes is an example of an atavism.
