The zoology book app will help you acquire subject-specific skills in the study of animal behavior; physiology, genetics and biology of animal species; understanding of ecological and conservation issues, and good laboratory practices. Useful transferable skills that you can develop on problem solving and decision making. Industries that employ zoologists include zoos and nature reserves, conservation and charity organizations, universities, scientific and field research organizations, and environmental consultants. This application will help you learn all the basic science of zoology.

Zoology is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek , zōion ('animal'), and , logos ('knowledge', 'study').

Although humans have always been interested in the natural history of the animals they saw around them, and made use of this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. The Greek physician Galen studied human anatomy and was one of the greatest surgeons of the ancient world, but after the fall of the Western Roman Empire and the onset of the Early Middle Ages, the Greek tradition of medicine and scientific study went into decline in Western Europe, although it continued in the medieval Islamic world. Modern zoology has its origins during the Renaissance and early modern period, with Carl Linnaeus, Antonie van Leeuwenhoek, Robert Hooke, Charles Darwin, Gregor Mendel and many others.

The study of animals has largely moved on to deal with form and function, adaptations, relationships between groups, behavior and ecology. Zoology has increasing been subdivided into disciplines such as classification, physiology, biochemistry and evolution. With the discovery of the structure of DNA by Francis Crick and James Watson in 1953, the realm of molecular biology opened up, leading to advances in cell biology, developmental biology and molecular genetics.
