An introductory activity exploring the process of natural selection in action using the Avida-ED simulation.
Observe the process of natural selection in action: beneficial mutations will randomly occur for some individuals, these mutant organisms will have a greater fitness due to their adaptation to the environment and will tend to increase in frequency in the population over successive generations.
Student Learning Goals
- Students will be able to explain the concept of fitness as used in biology, and that an organism’s fitness may change, depending upon its environment.
- Students will be able to explain the process of adaptation by natural selection, leading to genetic frequency change in a population over many generations.
- Students will be able to explain that natural selection is non-random.
