This document defines key terms related to biodiversity such as genetic diversity, species diversity, habitat diversity, and species richness and evenness. It also defines evolution, natural selection, speciation, and reproductive isolation. Additionally, it outlines the role of plate tectonics and isolation in forming new species, examples of mass extinctions, and the mechanism of natural selection. Finally, it discusses threats to biodiversity such as habitat destruction and loss, sustainable development versus conservation, and strategies for conserving biodiversity including habitat and species approaches.
