Historically, the most common type of identification key is the dichotomous key , a type of single-access key which offers a fixed sequence of identification steps, each with ...
In biology, determination is the process of matching a specimen or sample of an organism to a known taxon, for example identifying a plant as belonging to a particular species. Expert taxonomists may perform this task, but structures created by taxonomists are sometimes used by non-specialists.

Identification in biology is the process of assigning a pre-existing taxon name to an individual organism.Identification of organisms to individual scientific names (or codes) may be based on individualistic natural body features, [1] experimentally created individual markers (e.g., color dot patterns), or natural individualistic molecular markers (similar to those used in ...

Systematic biology (hereafter called simply systematics) is the field that (a) provides scientific names for organisms, (b) describes them, (c) preserves collections of them, (d) provides classifications for the organisms, keys for their identification, and data on their distributions, (e) investigates their evolutionary histories, and (f ...
