Zoology: Principles and Concepts

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.
