In a way that relates to the classification of living things into groups based on their characteristics.
The species were classified taxonomically to understand their evolutionary relationships.
Taxonomically → It is formed from "taxonomy" (from Greek "taxis" meaning arrangement and "nomia" meaning method or law) and the suffix "-ally" (meaning in a manner relating to). The word "taxonomically" refers to the manner of arranging or classifying organisms according to their relationships.
Think of 'taxonomy' as the method of arranging things, and '-ally' means in a manner. So, taxonomically means in a manner related to the arrangement of classifications.
