The document outlines 5 categories of evidence that are commonly used to support the theory of evolution: fossil record, DNA/protein sequences, biogeography, homology, and embryology. The fossil record provides evidence of how life forms have changed over time by examining the placement of older and younger fossils. DNA and protein sequence comparisons between organisms suggest common ancestry. Homology refers to similarities in structure and physiology between species. Embryology studies how development reveals relationships between species and their evolution.
