True
Plesiomorphies are derived character states.
False
Study Notes
Phylogeny and Classification
- Phylogeny is the study of the evolutionary or genealogical relationships among organisms.
- The Linnaean System is a hierarchical classification system that reflects the evolutionary history of organisms.
Classification of Organisms
- The Linnaean System classifies organisms based on their physical characteristics.
- Binomial nomenclature is a hierarchical classification system used in the Linnaean System.
Inferring Phylogenetic History
- Phylogenetic history is inferred based on two main factors: similarity and common ancestry.
- Similarity refers to the physical characteristics shared among organisms.
- Common ancestry implies that organisms share a recent or distant ancestor.
Character States
- Plesiomorphies are not derived character states, but rather ancestral character states.
- Derived character states are those that have evolved from ancestral character states.
Taxonomic Categories
- The largest taxonomic category in the Linnaean System is the domain.
