📖 Comprehensive Study Notes Summary
### Biological Classification
Classification is the arrangement of living organisms into groups based on their evolutionary relationships and shared characteristics.
#### Types of Classification Systems
1. **Artificial Classification**: Based on a few observable arbitrary features (e.g. habitat or mode of locomotion). Example: Grouping birds, bats, and insects together because they fly.
2. **Natural Classification**: Based on homologous structures, evolutionary relationships (phylogeny), anatomy, and biochemical similarities.
#### Taxonomic Hierarchy
Domain -> Kingdom -> Phylum (or Division) -> Class -> Order -> Family -> Genus -> Species
#### Rules of Binomial Nomenclature (Carl Linnaeus)
1. Every organism has a two-part Latin name: Genus (capitalized) + species (lowercase).
2. When typed, it must be italicized (Homo sapiens); when handwritten, each word must be underlined separately.
