The scientific process for determining the causes of diseases involves a systematic approach, typically starting with observations. Researchers form hypotheses about potential causes, conduct experiments, and gather data through epidemiological studies or clinical trials. This is followed by statistical analysis to determine correlations and establish causation. Validation through peer review and reproducibility of results is crucial to ensure the findings are credible. Additionally, advancements in molecular biology and genomics have enriched this process, enabling the identification of genetic and environmental factors contributing to various diseases.
