The Biology Corner Concept Cartoons These concept cartoons were developed by Dianne Anderson and Kathleen Fisher (2002) as prompts for eliciting discussion about ideas in evolution. They can also be used as assessment tools. The cartoons are best suited for college non-majors and pre-college classes. The incorrect statements in the cartoons are derived from common naive conceptions. Cartoons can be downloaded in PDF format and can be transferred to transparencies or paper copies so long as the copyright notation to Anderson and Fisher is retained.
