The most impractical statement that is unlikely to be informed by taxonomy is:
"Watching species as they evolve in real time gives us the opportunity to name and classify new organisms as speciation occurs."
While taxonomy does involve the classification and naming of species, observing evolution in real time is a complex and often indirect process. Taxonomy typically deals with the classification of organisms based on existing knowledge of their characteristics and relationships rather than being able to effectively name and classify new species as they evolve on an ongoing basis. The other statements relate more directly to established functions and benefits of taxonomy.
