Study Notes
Phylogenetic Classification
- Classification systems based on evolutionary relationships between organisms are currently acceptable, assuming a common ancestor for organisms within the same taxa.
Resolving Classification Difficulties
- Information from multiple sources is used to resolve classification difficulties, particularly when fossil evidence is lacking.
Numerical Taxonomy
- Numerical Taxonomy is a method that uses computers to analyze all observable characteristics of an organism.
- Each characteristic is assigned a number and code, and data is processed to give equal importance to each character.
- Hundreds of characteristics can be considered simultaneously using this method.
Additional Taxonomic Approaches
- Cytotaxonomy: uses cytological information such as chromosome number, structure, and behavior to resolve classification difficulties.
- Chemotaxonomy: uses the chemical constituents of plants to resolve classification confusions.
