Study Notes

Taxonomy Levels

The level of taxonomy with the fewest organisms is Species.
Honey bees belong to the classification level Insecta.

Classification and Evidence

Carl Linnaeus utilized physical characteristics as evidence for classifying organisms.
The taxonomic group that encompasses kingdoms and all other levels of taxonomy is known as the Domain.

Phylogenetics

A phylogenetic tree is a branching chart representing the evolutionary relationships among organisms.
Changes in a phylogenetic tree are least likely to stem from physical characteristics.
The classification of organisms is subject to change with new discoveries and technologies.

Common Nomenclature

Different species may share the same common name, illustrated by the Robin species: one in England with a yellow breast and one in the U.S. with a red breast.

Importance of Classification

Classifying the millions of species on Earth is crucial for their organization and to facilitate accurate communication about them.
