The Grants' study of Galápagos finches, conducted by biologists Peter and Rosemary Grant, focused on the evolutionary adaptations of these birds in response to environmental changes. They observed and documented natural selection in action, particularly during periods of drought, which affected food availability and influenced beak size and shape. Their research provided crucial evidence for Darwin's theory of evolution, demonstrating how species can adapt rapidly to changing conditions. This long-term study has become a landmark example of evolutionary Biology in practice.

What two animals was fascinating to Darwin?
The Galapagos finches and the Galapagos tortoises.
Where did Charles Darwin study finches?
The Galapagos Islands, which are about 600 miles off the coast of Ecuador.
What was the enviornmental challenge in the Grants' study?
The environmental challenge in the Grants' study was a severe drought that occurred in 1977 on the Galápagos Islands where they were studying finches. This drought caused a shortage of food, particularly the small seeds that the finches relied on for survival.
