Scientific method is an approach employed by biologists for gathering information. Based on observations, or data in the scientific literature, scientists formulate a hypothesis. It is possible to prove a hypothesis false, but it cannot be proven true. Scientists observed prevalence of dark-colored moths on sooty trees in polluted regions. If birds selected moths by color, then if equal numbers are released, birds will eat mostly one color.
