The way species spread out across different places gives strong support to the idea of evolution.
Island Biogeography: In isolated islands, we find unique species. A great example is the finches from the Galápagos Islands. These birds have developed different beak shapes so they can eat different types of food. This shows how being cut off in one place can lead to new species forming.
Continental Drift: Some species on continents that used to be connected share similarities. For example, in Australia, there are marsupials, while most other places have placental mammals. The fossils of the now-extinct Thylacine show how these species are linked across continents.
Climatic Zones: Different environments create various paths for evolution. Look at cacti in North America and euphorbias in Africa. Both have adapted to dry places, even though they aren't related. This is an example of convergent evolution.
These examples show that species change and develop in response to their surroundings over time.
