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.
