Biology is a natural science that studies living things. It has broad field due to the wide variety of life, so biologists normally focus on specific fields. These fields are either categorized by the scale of life or the types of organisms studied. The scale of biology can cover everything from genetics, biochemistry and molecular biology. There is also anatomy, physiology and other fields that focus on whole organisms such as animal behavior, population biology, ecology and systematics.
Other fields of biology are microbiology, virology, botany, zoology, wildlife biology and marine biology. And often, biologists focus on both a particular scale and a particular organism.
The most interesting recent discoveries in biology have happened in biochemistry, biophysics, bioengineering, and computational biology. These are important in the future. Other biology-based professions are medicine, nursing and allied health, pharmacy and pharmacology, dentistry and veterinary medicine.
