Biogeography reveals patterns of distribution and migration from "summary" of The Greatest Show on Earth by Richard Dawkins
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. By examining the patterns of distribution of plants and animals around the world, scientists can gain insights into how species have migrated and evolved over time. These patterns provide valuable information about the history of life on Earth and the factors that have shaped it. One of the key insights from biogeography is that species tend to be more closely related to other species that are geographically closer to them. This is known as the principle of biogeographic affinity. For example, species on islands are often more closely related to species on nearby continents than to species on other distant islands. This pattern can be explained by the fact that species are more likely to migrate and colonize nearby areas than distant ones. Another import...
