Models of DNA evolution refer to various theoretical frameworks and methodologies used to understand how DNA sequences change over time within and between species. These models can help in studying evolutionary relationships, tracing lineage, and understanding the mechanisms of mutation, gene flow, and genetic drift that drive evolution. Here are some key models and concepts associated with DNA evolution: 1. **Molecular Clock Hypothesis**: This hypothesis posits that DNA and protein sequences evolve at a relatively constant rate over time.
