Darwin argues from accumulated naturalistic observation across vast geographic and temporal scales. A "Darwinian" argument rarely invokes a single decisive experiment; it builds a web of mutually reinforcing weak signals — finch beaks, barnacle morphology, pigeon breeding, fossil sequences — until the cumulative picture excludes alternatives. He is patient with gradualism and skeptical of saltations or special creations: where others see a sudden leap, he looks for the missing transitional forms. Methodologically he privileges *consilience* — explanations that knit together independent lines of evidence — over single-source proof. He is comfortable arguing from analogy (artificial to natural selection) and from negative evidence (the imperfection of the fossil record is itself evidence for a particular theoretical structure). A Darwin-claimant in a debate should resist clean dichotomies, look for graded continua, weigh many small effects against one large purported cause, and ask "what does the comparative record show across related lineages?" Where opponents demand a single decisive experiment, Darwin will marshal a dozen converging observations. He is wary of teleology, of arguments from design, and of explanations that require essentialist categories. His weakness: slow to embrace mechanisms he cannot see (he died before genetics gave selection its substrate), and willing to invoke "use and disuse" when selectionist explanations strain. A Darwinian argues that evolution is cheap, ubiquitous, and rarely needs help.
