Study Notes
Taxonomy Overview
- Carolus Linnaeus is recognized as the Father of Taxonomy and introduced the binomial nomenclature system for naming species.
- Taxonomy is the science of organizing, classifying, and naming living organisms based on shared characteristics.
Levels of Classification
- The hierarchical structure includes the following eight levels: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
- Organisms that share higher classification levels (like Class) also share the ones below it (like Phylum).
Scientific Names
- Each species has a unique scientific name consisting of two parts: Genus and Species (e.g., Hypsibius dujardini).
- In scientific naming, the genus is capitalized while the species is written in lowercase.
Domains and Kingdoms
- The three domains of life are Bacteria, Archaea, and Eukarya.
- Eukarya contains four kingdoms: Animals, Plants, Fungi, and Protists; humans are classified under the kingdom Animalia.
Organism Types
- Prokaryotes lack a nucleus; all bacteria fall under this category.
- Organisms can be classified as unicellular (single-celled) or multicellular (many-celled).
Feeding Habits
- Organisms are categorized by their feeding habits: Herbivores eat only plants, Carnivores consume other animals, and Heterotrophs cannot produce their own food.
Identification Tools
- Taxonomists use dichotomous keys to identify unknown organisms based on specific traits.
- Example: A tree with brown cones and sharp needles is classified as a Spruce.
Organism Properties
- The more classification levels two organisms share, the more closely related they are.
- Almost all bacteria are heterotrophic, deriving their energy from other living organisms.
Importance of Scientific Names
- Scientific names eliminate confusion since no two species share the same name, ensuring clarity in research and communication.
