Biogeography

Biogeography is a science that attempts to describe the changing distributions and geographic patterns of living and fossil species of plants and animals. It is also concerned with the factors responsible for the variations in distributions. It therefore wants to answer questions as to where do species occur, how the species got to be where they are, and where are the greatest concentrations. It also tries to explain in part the causes of biodiversity.
