Testable and Falsifiable: Scientists can make specific predictions about the natural world and test them through observation and experimentation. For example, genetics allows scientists to predict how DNA changes over generations.

Based on Empirical Evidence: Evolutionary biology is backed by data from multiple independent fields, including paleontology (fossil records), genetics (DNA sharing), comparative anatomy (homologous structures), and biogeography (geographic distribution of species).

Observable Mechanisms: The core drivers of evolution—such as mutation, natural selection, genetic drift, and gene flow—can be directly observed, measured, and tested in laboratory settings and in wild populations.

Predictive Power: Evolutionary theory allows scientists to make accurate predictions in medicine and biology, such as tracking how bacteria develop antibiotic resistance or how viruses mutate over time.
