Using two websites students will examine different types of adaptations to study the direction of evolution in each case. The focus will be to see how sex, coevoution and mutations drive the direction of evolution. The students will read a comic story about crickets in a story entitled. "Survival of the Sneakiest" to study the impact of chirping to find a mate. The second website studies the coevolution of a newt and a snake by viewing a videoclip. The pressure to adapt comes from the interaction of species. Also using a videoclip, the third study examines how a mutation has altered an organism to survive in an environment. This video tells the story of sickle cell anemia and malaria, the origin of the sickle cell gene and its impact on the malarial organism to help to protect humans against malaria.
