Naming of organisms, genus, species
Match the following nomenclature rules with their descriptions:
Match the following nomenclature rules with their descriptions:
One name per organism = Only one correct name for each organism. Not after yourself = Names should not be personal. Latin or Greek = Use of classical languages for names. Be descriptive = Names should indicate characteristics. Location origin = Names could reflect geographical origin. Whimsical = Creative names are acceptable. No common name = Avoid using common names.

Study Notes
Classification
- Involves ordering species based on identifiable patterns and organizational principles.
Nomenclature
- Refers to the systematic naming of organisms, including levels such as genus and species.
Nomenclature Rules
- Each organism should have one distinct name.
- Names should not be derived from the name of the person describing the organism.
- Utilizes Latin or Greek for naming origins.
- Descriptive names are encouraged, possibly incorporating the location of origin or whimsical attributes.
- Avoids using common names for scientific classification.
Monophyletic
- Grouping includes an ancestor and all of its descendants, representing a complete lineage.
Paraphyletic
- A grouping that consists of an ancestor but excludes some of its descendants, leading to incomplete representation of evolutionary relationships.
Polyphyletic
- Refers to a group that may derive from two or more distinct ancestors, lacking a single common lineage.
Character
- Attributes or features of organisms are used to indicate evolutionary relationships and distinguish species from one another.
Phenotypical
- Involves observable traits such as shape and color that can help identify and classify organisms.
Molecular
- Refers to genetic components including DNA, RNA, and genes, which are used in modern classification methods.
Homologous
- Traits that are similar due to shared ancestry, emphasizing common origins at the genetic level.
Plasiomorphy
- Common traits that serve as the foundational characteristics at the base of a phylogenetic tree.
Apomorphy
- Refers to specialized traits that have evolved from ancestral forms, highlighting divergence within lineages.
