Scientific name is a binomial. System was started by Swedish naturalist Carolus Linnaeus. Science Helps Human Beings Understand the Natural World. Scientific investigation is limited to questions that can be studied objectively. Scientific conclusions are subject to change when new techniques and equipment are available.
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. Conclusions from new data support hypothesis that birds are responsible for distribution.
