This series explains the concept and need for classification and explores the key features and characteristics of each classification group. The books explain how living things within a classification group can be linked by key aspects such as behaviour, life cycle, appearance and structure. They start with an introduction to classification - how classification helps us to group animals and plants, the systems, such as kingdoms, and the use of scientific and common names. The books then progress into exploring the specifics of a particular class and provide examples from significant orders. The series also looks at examples which may appear to belong to one group, but in fact belong to another.
