The question asks which of the listed approaches is used to study the origin of life on Earth. 
Option 1: Phylogenetics. This method focuses on evolutionary relationships among existing organisms or genes, usually reconstructing lineages rather than directly modeling the origin of life itself. It helps trace how life diversified after origin but does not simulate how life began. 
Option 2: Computer modeling. This approach uses computational simulations to explore hypotheses about prebiotic chemistry, formation of protocells, and early Earth conditions, allowing researchers to test how simple molecules could assemble into more complex systems. It is a common tool for origin-of-life research because it can integrate multiple variables and scenarios that are difficult to test experimentally. 
Option 3: Comparative anatomy. This field compares body structures across organisms to infer evolutionary relationships and functional adaptation. While informative about later evolution, it is not a primary method for investigating how life originated. 
Option 4: Fossil analysis. Fossil evidence informs about ancient life and its morphology, ecology, and timing, but actual origin events are typically inferred from chemical, geological, and modeling data; fossils alone do not directly reveal the initial emergence of life. 
Option 5: Molecular clocks. This technique estimates divergence times based on genetic change rates, useful for dating evolutionary events after life began, not for uncovering the origins of life itself. 
In summary, while several methods illuminate the history of life, computer modeling uniquely serves as a key tool for exploring origin-of-life scenarios by simulating chemical networks, environmental conditions, and potential pathways to complexity. The stated correct choice is Computer modeling, which aligns with its role in origin-of-life research.
