Study Notes

Taxonomic Hierarchy

  • Taxonomic classification organizes living organisms into a structured system based on shared characteristics.
  • The hierarchy consists of several levels, each representing a rank of classification.

Kingdom

  • Represents the highest taxonomic rank.
  • Composed of smaller groups known as phyla (or divisions in plants).

Phylum

  • Positioned below Kingdom and above Class in the classification hierarchy.
  • Defines a major group of related organisms, particularly significant for animals.

Class

  • A classification level that groups related organisms displaying similar characteristics, attributes, or traits.
  • Serves as an intermediary rank between Phylum and Order.

Order

  • A rank in the taxonomic hierarchy that falls below Class and above Family.
  • Comprises families that share similar characteristics and are related in nature.

Family

  • Taxonomically positioned between Genus and Order.
  • Groups organisms that are closely related and share a common lineage.

Genus

  • A classification that groups together species based on shared attributes.
  • Serves as a way to cluster closely related species under a common name.

Species

  • Represents the lowest taxonomic rank and is the fundamental unit of biological classification.
  • Defines a group of individuals that can interbreed and produce fertile offspring, exhibiting shared traits and behaviors.
