This new volume full explores zoology, the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habit, and distribution of all animals, and how they interact with their ecosystems.

Emphasizing the central role of evolution in generating diversity, this best-selling text describes animal life and the fascinating adaptations that enable animals to inhabit so many ecological niches. Featuring high quality illustrations and photographs set within an engaging narrative, Integrated Principles of Zoology is considered the standard by which other texts are measured. With its comprehensive coverage of biological and zoological principles, mechanisms of evolution, diversity, physiology, and ecology, organized into five parts for easy access, this text is suitable for one- or two-semester introductory courses.

Zoology is a branch of biology that studies the animal kingdom. This encompasses the study of structure, classification, embryology, habit and distribution of animals, whether extinct or living, and their interactions with their environment. Structural studies in zoology are approached from the domains of cell biology and anatomy. This enables the study of unicellular and multicellular organisms from the perspective of the structure and function of cells, organs and organ systems. Physiology studies how the different structures of a living organism function as a whole. The origin and descent of species, and their change over time is tackled in evolutionary biology. The grouping and categorization of organisms based on their genus or species allows ease of study and research and is known as scientific classification. It is considered an important aspect of zoology. This book discusses the fundamentals as well as modern approaches of zoology. It unravels the recent studies in this field. It will prove to be immensely beneficial to students and researchers in this field.
