Question
Chapter 26.1, Problem 1CC
Summary Introduction
To determine: The broader group between a phylum and a family.
Introduction: The system of classification was given by Carolus Linnaeus. In this system, animals were divided specifically on the basis of their characteristics. The purpose of subdividing the animals into small taxonomic groups is to appreciate the relationship among a large number of species.

Linnaeus' Classification System:
The first major step in naming organisms wastaken by
Linnaeus used a hierarchical system of classification with seven levels.
They are from largest to smallest: kingdom, phylum, class, order, family, genus, species.
King Phillip Came Over From Greece Singing.
Each of these levels is called a
- largest category, group of related phyla.
- group
