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."
This statement implies a continuous and immediate process of naming and classifying organisms during ongoing evolutionary processes, which is not practical. Taxonomy typically involves the study and classification of organisms based on existing characteristics rather than in real-time observation of speciation events. The other statements emphasize the utility of taxonomy in understanding ecosystems, recognizing potential benefits of organisms, and tracing evolutionary history, which are all practical applications of taxonomy.
