Biology literally means the study of life. There are many different types of living organisms, environments, and combinations of genetic material. The science of biology includes all information related to studying living things, but a biologist does not and cannot study every facet of all living things. It would just take too much time. So, biologists specialize in certain areas of biology and focus their research.

With each specialist studying details of certain biological areas, the information can be pooled (usually at big conferences) and shared to make the knowledge base a bit wider. And that’s what science is: a continually growing knowledge base focused on things in nature, whether those natural things are banana trees, kangaroos, swordfish, dinosaurs, rocks, gases, or chemicals and cells that make up all of those things.
