Study Notes
Scientific Names
- Scientific name for house cat: Felis domesticus (in italics).

Linnaeus' Classification System
- Developed a hierarchy of 7 levels: kingdom, phylum, class, order, family, genus, species.
- Classification based on structural differences among organisms.
Binomial Nomenclature
- A two-word naming system for organisms: genus followed by species.
- Created by Carl Linnaeus.
Historical Classification
- Aristotle is recognized as the first to classify living organisms.
Taxonomic Domains
- Domains are the highest taxonomic category, ranking above kingdoms.
- Three domains: Archaea, Bacteria, Eukarya.
Aristotle's Animal Groups
- Divided animals into three groups: land dwellers, water dwellers, air dwellers.

- Branch of biology focused on naming and classifying species.
Importance of Scientific Names
- Scientific names eliminate confusion found in common names, which often vary by region; e.g., Puma, mountain lion, and cougar refer to the same animal.
Levels of Classification
- Kingdom is the broadest classification level in Linnaeus' system.

Classifying Organisms
- Classifying involves grouping based on similarities among organisms or objects.
