Chapter 17.1, Problem 3MI

Summary Introduction

To classify:

The given terms as being part of Linnaeus’ two- word naming system or a taxonomic group.

Introduction:

Taxonomy is study of identifying, naming and classifying species based on natural relationships. The taxonomic categories are part of a nested hierarchal system- each category is contained within another, as they are arranged from broadest to most specific.

Linnaeus’s system of classification was the first formal system of taxonomic organization. His method of naming organisms is called binomial nomenclature.

Answer to Problem 3MI

Linnaeus’ System	Taxonomic Group
Binominal Nomenclature Genus	Class Division Domain Family Kingdom Order Phylum

Explanation of Solution

Linnaeus’s method of naming organisms is called binomial nomenclature. It gives each species a scientific name which is written in two parts; a genus name and a specific name. The widespread use of this system has made it very popular.

A named group of organisms is called a taxon. Taxa range from broad diagnostic categories to having specific characteristics. The broader the characteristics, the more species the taxon contains. The taxa are organized into a hierarchical system. The different taxonomic categories are species, genus, family, order, class, phylum, kingdom and domain. Domain is the broadest category and species is the smallest category.
