The comparison of taxonomy to a grocery store's departments is meant to show that taxonomy is:

1. The analogy is chosen to set expectations about what classification does. 2. Taxonomy is a tool to organize the millions of organisms on Earth. 3. That is similar to how items in a grocery store or mall shop are organised into different departments. 4. Departments are a convenience imposed on the goods rather than a fact about them. 5. The evolutionary claims live in the phylogenetic tree rather than in the filing system. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 20 'Phylogenies and the History of Life', sections 20.1-20.3_
