A dichotomous key is a tool used in biology and other sciences to identify organisms, species, or objects based on a series of choices that lead the user to the correct name or classification. The key consists of a series of paired statements or questions that describe characteristics of the organisms.
Each pair presents two contrasting options, and the user must choose one based on the characteristics of the specimen being identified. Following the chosen path through the key eventually leads to a specific identification. Dichotomous keys are commonly used in fields such as taxonomy, ecology, and environmental science to facilitate the identification of plants, animals, fungi, and other organisms.
For example, a simple dichotomous key for identifying a leaf might start with questions about whether the leaf is broad or needle-like, then proceed based on additional features until a specific type of leaf is identified.
