What is Biology

Simply said, biology is the study of life.

Biologists now agree that life is a product of a certain set of processes that arise from the arrangement of matter. 

Biologists have compiled a list of features that define the “set of life processes” shared by all organisms as living:  The living:

  • Use up stuff and power.
  • To have offspring; to perpetuate one’s genes.
  • Evolve and expand.
  • Demonstrate inherited differences or variants.
  • Are well-suited to their natural habitat.
  • React to external influences.

The scientific nature of biology has led to the categorization of life’s defining features into the following categories:

  • Harmony and Variety
  • Constancy in Genealogy
  • Characteristics of Human Nature
  • Harmony between Form and Operation
  • Organism-Environment Interactions
  • Evolution

All of the Life Science classes have a common thread of these key ideas.
