exist in their eyes. The hierarchies generated by their studies are not arbitrarily spaced, which therefore clearly implies a taxonomic structure. The plants still have a part in their lives and they still identify with them even though they may not have a name. The process of having a given a name to certain life forms in their ecology shows just how much these people are attached to their surroundings. It also shows what to them is considered a life form and what is not. The study proves that we should not take shallow taxonomic hierarchies for granted and should have further studies concerning them to show that the different languages go deeper than we actually let on to them. The study helps outline three great studies that others can use to set up their own studies. It can help researchers understand why sometimes it is hard to identify where the midlevel on a taxonomy hierarchy is or even if it exists at all in a certain community. General Principles of Classification and Nomenclature in Folk Biology (1973) One of the first works Berlin published in relation to the budding field of ethnobiology was also one of his more influential: General Principles of Classification and Nomenclature in Folk Biology (1973) was coauthored with Dennis Breedlove of the California Academy of Sciences and Peter Raven of the Missouri Botanical Garden. In this journal article, Berlin and team intended to illustrate three hypotheses they felt were properly supported by the data they had acquired during the research they completed. First, it is possible to isolate organisms into linguistically recognized groups called taxa, or classes. Second, these taxa can be further broken down into no more than five smaller classes called taxonomic ethnobiological categories. These smaller categories are defined in terms of certain criteria, such as having certain linguistic or taxonomic feature that are recognizable. They continued to describe how these organisms, flora or fauna, belonging to each of these categories can be arranged into a complex taxonomic hierarchy. The five ethnobiological categories are as follows: unique beginner, life form, generic, specific, and varietal. Most, if not all organisms can be placed taxonomically into these categories. They turned their attentions to the formal linguistic structure of the lexemic nomenclature of the plants and animals and to which taxa each of these organisms belong to. After laying out the criteria and division of the
