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.
