He grouped organisms by their modes of transportation: swimming, walking, flying, etc. As centuries went by, scientists began grouping organisms into categories based on their physiological appearance. This means that scientists observe the anatomical structures and the how the organisms use these structures in nature. Carl Linnaeus was the not the first man who noticed organisms had similar characteristics as well as unique structures; however, he was the first person to create a system that gives each species a unique name. Shown below is an example of this naming structure for a common honeybee — Apis mellifera. Embryology and Ontogeny.

Teacher professional development and classroom resources across the curriculum. A hierarchical system is used for classifying organisms to the species level. This system is called taxonomic classification. The broadest classifications are by domain and kingdom; the most specific classification is by genus and species. The hierarchical groupings in between include phylum, class, family, and order. Species are the basic unit of classification.

They had to know what was safe to eat or to use in various ways, as well as what organisms could harm them.
