Definition of Biology – What is Biology?

Biology is a branch of science that deals with the study of living things.

There are diverse forms of life on earth ranging from the invisible microscopic living things to the gigantic life forms. It aims at explaining the living world in terms of scientific principles.
It is important to note that living things interact with non-living things in the environment as well.
Biology, therefore, also entails the study of non-living things. The role of human beings in shaping the environment is also investigated in biology.
In summary, biology deals with the study of origins, types, nature, growth, development, interactions, and maintenance of all life forms on earth.

Importance of Biology

The study of biology is very important. The knowledge acquired from this study can benefit an individual in many ways, including:

The knowledge gained can help solve environmental problems such as food shortages, poor health services, pollution, and environmental degradation.
The study of biology can grant one entry into careers such as medicine, veterinary medicine, animal husbandry, horticulture, and dentistry.
Biology develops scientific skills such as observing, identifying, recording, classifying, measuring, analyzing, and evaluating. These skills help individuals make better choices and improve their lives.
Through biology, humans learn the causes of plant, animal, and human diseases and how best to prevent and cure them.
Biological knowledge enhances international cooperation. Some biology-related international collaborations include:

Joint development of the HIV/AIDS vaccine by Kenyan and British scientists.
