Description

Students are asked to explain why so many finches died during the drought of 1977 in the Galapagos and what enabled the remaining finches to survive. This investigation is preceded by several lab experiences that build understanding about environmental stress, trait variation, acquired characteristics, generational change and bird beak form and function.
