Introduction

Watch the video to find out how the Floreana mockingbird helped inspire Darwin's theory of evolution by natural selection and how, more than 170 years later, 2 of the specimens collected during the Beagle voyage are helping efforts to save this species from extinction.Though Darwin knew nothing of DNA, the Floreana mockingbird specimens he and FitzRoy collected have, after 170 years of safe-keeping in collections, yielded genetic clues to suggest a path for conservation of this critically endangered and historically important species.

Darwin's inspiration
When Darwin visited the Galápagos archipelago in 1835 aboard HMS Beagle, he was struck by the slight differences between the mockingbirds he found on the different islands. He wondered if the mockingbirds on each island might be modified descendants of a single, ancestral species that had migrated to the islands at some time in the past.This clue led him to question the stability of all species and set him on the road towards the theory of evolution by natural selection and his most famous work On the Origin of Species.
