We are working on genetics, and just took that the next step to see how genetics would change as the process of natural selection was happening to a population.
To do this, students made origami frogs as seen in this video:
The frogs have 4 different "genes" that can be varied:
- The size of the starting paper (3 or 5 inches square)
- The number of folds that make the jumping mechanism (2 or 3)
- The color of the paper (either reddish or greenish which the students colored)
- The stiffness of the paper (regular paper or index card)
The results are pretty neat so far. There is a very clear type of frog that is most common, but the other types of frogs continue to pop up in the gene pool. Neat to see some genetic diversity from a simple set of genes and some clear microevolution as well.
