Full Answer

Domain and kingdom are the broadest taxonomic classifications available. All animals belong to the kingdom Animalia, but each species has different characteristics. Genus and species are the most narrow classifications available.

Each taxonomic level has unifying features. Organisms in the phylum Chordata, for example, all have a spinal cord. Members of the class Mammalia nurse their young.

Taxonomic classification allows scientists to identify natural patterns and explain how organisms are related to each other.

  • Q:

    What is classification in science?

    A:

    Classification, or taxonomy, is the process of identifying, naming and categorizing living things based on their physical and biological characteristics. According to the Natural History Museum, scientists believe there are more than 31 million species of micro-organisms, animals and plants living on Earth today. Classification of living things helps scientists and students organize their research. It also helps to explain the interrelationships among diverse groups of organisms.

  • Q:

    What is a biological key and how is it used?

    A:

    A biological key, also known as an identification key or a dichotomous key, is a way to classify organisms by giving the classifier two options in each stage until identification occurs. For example, in order to identify the tree, a biological key gives two choices – conifer or broadleaf – with a description of each one. Depending on the answer, another question pops up to narrow down the species.
