Study Notes
Aristotle's Classification
- Divided animals into two groups: Enaima (with red blood) and Anaima (without red blood)
- Classified animals based on environment: aquatic, terrestrial, and aerial
- Classified animals based on diet: carnivorous and herbivorous
- Classified animals based on reproduction: oviparous and viviparous
Natural Classification
- Groups animals based on structural similarities and evolutionary relationships
- Not based on superficial resemblance
John Ray's Contributions
- First systematist to use structural similarity for classification
- Defined 'species' as the largest group of organisms capable of reproducing and producing a fertile offspring
Linnaeus' Classification
- Published in "Systema Naturae"
- Made the study of animals convenient and indicated true evolutionary relationships
- Helpful in identifying animals
- Stimulated discovery and naming of new species
Modern Classification
- Expanded form of Linnaeus' classification
- Divided into phyla, classes, orders, families, genera, and species
Taxonomic Divisions
- Phylum: an assemblage of animals with common characteristics
- Class: a smaller group with characteristics of the phylum and more specific structural characteristics
- Order: a smaller group with characteristics of the phylum and class, and some common characteristics peculiar to the order
- Family: a smaller group within an order
- Genus: a smaller group within a family
- Species: a group of individuals with characteristics of the larger groups and its own identifying characteristics

Description
Explore Aristotle's system of classification for animals, which divides them into Enaima and Anaima based on the presence or absence of red blood. Learn how animals are further classified based on their environment (aquatic, terrestrial, aerial) and diet (carnivorous, herbivorous, omnivorous).
