From: Iterative design of a simulation-based module for teaching evolution by natural selection
Key concept Misconception | Description |
---|---|
Evolution by natural selection | Change in relative frequency of trait in a population |
 Need to change | Populations/organisms change traits because they need to |
 Individuals evolve | Evolution occurs because individuals change their traits |
 Gradual population change | Evolution occurs via gradual change in whole population (i.e., all individuals from one generation to the next) |
Variation | Trait variation in a population is necessary for natural selection |
Role of mutation | Mutation is a source of trait variation |
Mutations random | Mutations are random and unrelated to selective pressure |
 Adaptive mutation | Mutations are adaptive responses to the environment and are biased towards advantageous mutations |
Heritability | Heritability of a trait is necessary for natural selection |
 Beneficial traits | Offspring inherit only beneficial traits |
 Acquired traits | Acquired characteristics are inherited |
Differential fitness | Differential survival and/or reproduction necessary for natural selection |
