The Galápagos Islands hold a special place in the history of science. This isolated archipelago served as the living laboratory where Charles Darwin gathered observations that changed how we understand biology.
This quiz covers the unique wildlife of the islands, Darwin’s famous voyage on the HMS Beagle, and the evolutionary adaptations of species like giant tortoises and marine iguanas.
