Biology and Zoology are fields of study with particular characteristics that make them different from each other, however, both are closely related; for this reason, it is not surprising that they are very often confused. In fact, the line that separates these two fields is quite thin; as they are very similar in nature. DIFFERENCE BETWEEN BIOLOGY AND ZOOLOGY

If you have doubts about it or are simply looking for some information to complement what you already know about the difference between Zoology and Biology, then continue reading, because below we explain everything you need to know in around this interesting topic that is often left as homework at school or comes up while having any daily conversation.


This is the field of Natural Sciences that is responsible for the study of living beings in a 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 that biologists can focus on. 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 of 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 its main focus, it includes both aquatic and terrestrial animals and studies their structure, embryology, evolution, classification, habits and geographic distribution (without excluding extinct animals).

Zoology also studies how animals interact with their ecosystems. However, despite studying animals (without excluding any), 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, among which is Zoology itself.

Although human beings 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 be studied from the time of Aristotle, while the term Biology was used for the first time by the scientist Carlos Linnaeus.
