A video that shows that climate change can be a selective pressure in natural selection that can lead to the ‘evolutionary rescue’ of a species.
Students will learn about the Snowshoe hares in North America. They will understand how reduced snowfall due to a warming climate can behave as a selective pressure on the seasonal coat colour polymorphism of the species.
Use this tool to help students find answers to:
- What is genetic polymorphism?
- What is selective pressure? How could climate change act as a selective pressure in the evolution of a species of organisms?
