Study Notes
Biological Classification
- Early attempts to classify living organisms were often based on practical needs (food, shelter) rather than scientific criteria
- Aristotle was one of the earliest to attempt a scientific classification system, using simple morphological characteristics to classify plants (trees, shrubs, herbs) & animals based on whether they had red blood.
- Linnaeus developed the Two Kingdom system (Plantae & Animalia) which categorized organisms based on their overall characteristics. This system, while simpler, was limited by its inability to distinguish characteristics of eukaryotes versus prokaryotes, unicellular vs multicellular organisms, or photosynthetic vs non-photosynthetic organisms.
- Over time, scientists realized that a more comprehensive classification system was needed that incorporated additional characteristics.
- The growing understanding of cellular structures, methods of reproduction, nutritional processes, & evolutionary relationships necessitated more complex systems.
- The number and type of kingdoms, used in classification, has changed over time. Modern classification systems are more detailed and nuanced.
