From: What can student-generated animations tell us about students’ conceptions of evolution?
E1—Variation between individuals | Any differences in phenotypes–phenotypic variation. Indications of variation present |
E2—Origin of variation | Variation arises at a genetic level. Coupling between mutations and the variation of traits is necessary |
E3—Inheritance (including reproduction) | Offspring inherit traits from parents and pass them on to successive generations |
E4—Differential survival | Not all individuals in a generation survive to reproduce for reasons such as limitations in resources or predator attacks |
E5—Change in population | Favourable traits become more frequent in populations over generations |
A1—Intentionality | Directed evolution where a new trait appears after a change in the environment. Indication that changes occur because of an ultimate goal or by human-like intentions and ability to plan for a distant future |
A2—Essentialism | Transformation of all individuals within a population. Unifying essence instead of variation |
A3—Natural selection as an event | Major evolutionary changes occur in less than threea generations |
T1—Organizational levels | Connections between organizational levels, from genes to population |
T2—Time | Illustration/manipulation of tempo. (Fast forward or slow motion) |
