Zoology is derived from the Greek words zoo (Animal) and logos (Study), the branch of biology that deals with the study of animals. From understanding animals’ behavior and anatomy to exploring their ecological role, zoology provides insights into the vast and diverse animal kingdom.
Humans have been fascinated by animals for centuries. Early cave paintings and records suggest that prehistoric humans closely observed animals to survive and understand their behavior. Today, many challenges are faced in zoology. Zoology helps in medical research, environmental conservation, and agricultural advancement.
Aristotle is regarded as a “Father of zoology” and was one of the scientists to study and classify animals. He was an ancient Greek philosopher who gave the first classification of animals. He said about nature “In all things of nature, there is something marvelous”.
Classification based branches:
There are some branches of zoology.
Entomology
It includes the study of insects, understanding ecosystems, pollination, and pest control.
Herpetology
The study of amphibians and reptiles is called herpetology
Ornithology
The branch of zoology that studies about birds is called ornithology. It explains the migration, behavior, and song communication of birds.
Ichthyology
It focuses on fish species, their habitat, and their ecological roles.
Mammalogy
It studies about mammals, their behavior, diet, physiology, and evolutionary history.
Functional Branches:
Anatomy
It explores the structures of the organisms.
Physiology
It studies how animals’ bodies function
Embryology
It examines the development of embryos from fertilization to birth, which is called embryology.
Ecological and evolutionary branches:
Ecology
The branch of zoology studies interactions between animals and their environment.
Etiology
It focuses on animal behavior in natural things
Evolutionary biology
This branch explains how animals evolved. It studied the evolutionary process (natural selection) that produced the diversity of life on Earth.

Why does matter?
1. Biodiversity conservation:
Zoology helps identify and protect endangered species and their habitat. It helps to promote biodiversity and maintain ecological balance. Zoology helps in learning about the extinction of biodiversity, their causes, and their impact on the environment.
2. Human health and medicine:
Research on animals can lead to medical advancements, such as vaccines, treatments, and other transmitted diseases. In university, we used many animals and birds for research purposes like rabbits, rats, and mice. We need animals as a food source. Today, hunting, fishing, and gathering wildlife is a significant source of food in the world. The meat sourced from wildlife is called bush meat.
3. Ecosystems
Animals play an important role in ecosystems as predators, prey, and decomposers. Many animals live in a community, and some in small groups. For example, vultures eat dead animals.
4. Economic Importance
Animals are very important for countries’ economies. They are vital for agriculture, tourism, and cultural practice. Markhor trophy in Pakistan is helping the economy of the country. Many national parks, game reserves, wildlife sanctuaries, and zoos are established to protect supporting economies and human livelihoods.
- The first zoological park was “Kruger Park”. It was established in 1895 in South Africa.
5. Scientific curiosity and education
Zoology expands our knowledge of the natural world, fostering curiosity and inspiring future generations to explore science. It explains the process of evolution, climate change, and other natural things.
6. Religion
Many animal species have significant importance in different religions of the world. For example, In Islam, Muslims conduct sacrifices on Eid al-Adha. Goats, cows, camels, and sheep may be offered as sacrifices during the three days of Eid. In Hinduism, the cow is regarded as sacred. In Native Americans, the feathers of eagles and hawks hold profound cultural and spiritual significance.
By studying zoology, we not only enhance our understanding of the animal kingdom but also contribute to solutions for global challenges like conservation, sustainability, and public health.
