Overview:
This comic follows the efforts of a male cricket as he tries to attract a mate, and in the process, debunks common myths about what it means to be evolutionarily "fit."Author/Source:
UC Museum of Paleontology Grade level:
9-12 Time:
10 minutes Teaching tips:
Use the questions at the end of the comic to stimulate class discussion on the concept of fitness. Concepts: - There is a fit between organisms and their environments, though not always a perfect fit.
- Traits that confer an advantage may persist in the population and are called adaptations.
- Inherited characteristics affect the likelihood of an organism's survival and reproduction.
- Over time, the proportion of individuals with advantageous characteristics may increase (and the proportion with disadvantageous characteristics may decrease) due to their likelihood of surviving and reproducing.
- Evolution does not consist of progress in any particular direction.
- Fitness is reproductive success - the number of viable offspring produced by an individual in comparison to other individuals in a population/species.
