    Study Notes

    Evolution of Classification Systems

    • Scientific study is an ongoing process, and new species and organisms are continually being discovered.
    • The initial system of classification focused on the habits and habitats of organisms.
    • Classification was later expanded to include external morphology as a key factor.
    • Morphology and embryology were subsequently incorporated into the classification system.
    • The phylogenetic relationship and cytology of organisms were also added to the classification process.
    • Modern classification systems utilize biochemical techniques to categorize organisms based on their nucleic acid components.
