Final answer:
Biogeography provides evidence for evolution by studying the distribution of species. Darwin's observations of iguanas in different regions support this idea.
Step-by-step explanation:
Biogeography is the study of the distribution of plants and animals across different regions. It provides evidence for evolution by showing patterns in the distribution of species that can be explained by common ancestry and adaptation to different environments.
For example, Charles Darwin observed that iguanas from the Galapagos Islands had different characteristics compared to those from South America. This variation in traits can be attributed to the different environmental conditions and selective pressures on each island.
This example demonstrates how biogeography can help support the theory of evolution by showing how species adapt and evolve in response to their specific geographic locations.
