Zoology, a branch of biology, is dedicated to the study of animal life forms within the kingdom Animalia.
Zoology encompasses a wide array of scientific disciplines, including morphology, anatomy, physiology, biochemistry, evolutionary biology, ecology, genetics, molecular biology, population genetics, taxonomy, and classification.
Zoology is the scientific study related to the entire species of the animal kingdom. An individual who specializes in the scientific study of animals (i.e., zoology) is known as a zoologist. Zoology is also known as animal biology.
The origins of zoology can be traced back to ancient times, with Aristotle being among the first to broadly classify living things into animals and plants. Over centuries, zoology has evolved significantly, especially during the Age of Enlightenment, when scientists began to conduct more in-depth research.
Today, the classification of living organisms has become more complex, with animals categorized into various phyla, classes, orders, families, genera, and species.
Zoology encompasses several sub-disciplines, each exploring specific aspects of animal life:
Each of these sub-disciplines contributes to our understanding of the diverse animal kingdom, from their structural and functional characteristics to their behavior, distribution, and evolutionary history.
