The cladist presented a new classification system for the species at the conference.
Cladist → It is formed from "cladus" (from Greek "klados", meaning branch) and the suffix "-ist" (meaning one who practices or is concerned with). A cladist is someone who studies or practices cladistics, which is a method of classifying organisms based on common ancestry and branching evolutionary relationships.
Think of a 'branch' ('cladus') of a tree representing different species, and remember that a 'cladist' is someone who studies these branches of life.
