The modern toucan species originated in South America during the Miocene period, around 23 million years ago. Toucans are closely related to barbets and are thought to have evolved from a common ancestor. Toucans and hornbills are an example of convergent evolution, having separately evolved similar adaptations to fill their shared niche on their respective continents.3 Sources
