Darwin's Finches and Evolution

The video discusses Darwin's observations of finches on the Galápagos Islands, highlighting their adaptations and the role of natural selection in evolution. It introduces the Galápagos as a unique ecosystem with diverse species and explains how Darwin's studies contributed to the theory of evolution. The video also mentions further research by Peter and Rosemary Grant, which supported Darwin's findings. Viewers are encouraged to support the channel and explore additional resources.
