Scientists use dichotomous keys as a tool to help identify unknown organisms based on their characteristics. The key presents a series of paired statements about the organism's features, with the scientist choosing the statement that best matches the organism they are trying to identify. By following the key and making choices based on the characteristics observed, scientists can narrow down the potential identity of the organism.

What do you use to classify things?
Classification is typically done based on shared characteristics or criteria. This can include properties such as size, shape, color, function, or behavior. Various systems and methodologies, such as taxonomies, algorithms, or categorization frameworks, can be employed to classify things.
Taxonomic keys are usually?
Taxonomic keys are usually a series of choices or questions that help users identify unknown organisms based on their characteristics or features. By answering these questions and following the given criteria, users can narrow down the options and arrive at the correct classification of the organism. These keys are designed to be systematic and dichotomous, leading users through a step-by-step process towards identification.
Are dichotomous keys based on a phylogenetic or morphological approach to classification?
Dichotomous keys are typically based on a morphological approach to classification, using observable physical characteristics to identify and classify organisms. This method involves sorting organisms into groups based on shared physical traits rather than evolutionary relationships.
Are taxonomic keys trichotomous?
Taxonomic keys can be trichotomous, meaning that they have three options at each step for identifying organisms based on specific characteristics. However, keys can also be dichotomous (two options) or multi-access (more than three options) depending on the complexity of the group being identified.
Who invented the dichotomous key?
The dichotomous key was developed by botanist John Ray in the 17th century. Ray's work on classification and taxonomy laid the foundation for modern dichotomous keys used in the identification of organisms.
