This document provides information about evolution, including definitions of macroevolution and microevolution. It outlines several pieces of evidence that support the theory of evolution, including the fossil record, selective breeding, and homologous structures. The key mechanisms of evolution - variation within populations, the struggle for survival due to overproduction of offspring, natural selection, and evolution in response to environmental changes - are also explained. Specific examples provided include antibiotic resistance in bacteria and changes in peppered moths.
