Essential Science for Teachers: Life Science

Evolution and the Tree of Life Bottle Biology

Bottle Biology Spotlight

To accompany Sessions 5 and 6, the “Field Population System” has been designed to demonstrate the fundamentals of evolution: variation, adaptation, and natural selection. What happens when an herbivore is introduced to three intermixed populations of plants? How might new species arise in this way? Check out Bottle Biology Spotlights to see how our experiment turned out, and for more information on building your own Bottle Biology systems.
