If you have doubts about it or just search for some information that complements what you already know about the difference between Biology and Zoology, then continue reading, because below we explain everything you need to know in around this interesting topic that is often left as a homework in school or arises while sustaining any daily conversation.


This is the field of the Natural Sciences that is in charge of the study of the a-live beings in general sense. This includes the study of life itself, as well as its structure, function, development, evolution, identification and taxonomy.

It is a very broad field of study, which is why it has been divided into several sub disciplines in which biologists can focus. Some of these sub-fields are: Biochemistry, Molecular Biology, Botany, Cell Biology, Physiology, Evolutionary Biology, Ecology, among many others. Each of these studies a different aspect within Biology.


On the other hand, Zoology is one among the many sub disciplines that Biology has. It is also known as animal biology, since it is responsible for the study of animals. Since animals are their main focus, it includes both aquatic and terrestrial animals and studies its structure, embryology, evolution, classification, habits and geographic distribution (not excluding extinct animals).

Zoology also studies how animals interact with their ecosystems. However, despite studying animals (excluding none), the study of humans (belonging to the animal kingdom) is not essential for this field. Finally, both fields are well respected; but it is always good to keep in mind that biology is more general and encompasses many disciplines, including zoology itself.

Although humans have been studying the things around them since they acquired the ability to think, the truth is that the fields of study were not always divided and organized until not so remote times. Zoology began to study from the days of Aristotle, while the term Biology was first used by the scientist Carlos Linnaeus.
