A genus of finches (Darwin's finches) found in the Galápagos Islands, famous for demonstrating evolution.
From 'geo-' (earth) plus Greek 'spiza' (finch), the scientific name literally means 'Earth finch,' likely referencing their ground-dwelling habits.
Geospiza finches are evolution's poster children—Darwin noticed that each island had slightly different beak shapes, and this observation became crucial evidence that species adapt to their environments, revolutionizing biology.
