The example of taxonomy among the given options is:
1. Researchers discover a new animal species and publish an official record of the scientific classification for that species.
This option aligns with taxonomy, which is the science of classification, where organisms are categorized into groups based on shared characteristics. When researchers discover a new species, they analyze its characteristics and place it into the appropriate taxonomic groups based on similarities with other known species. By publishing an official record of the scientific classification, they are contributing to the field of taxonomy by organizing and categorizing the newly discovered species within the existing classification system.
