Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution.

There are generally considered to be at least nine "umbrella" fields of biology, each of which consists of multiple subfields.

  • Biochemistry: the study of the material substances that make up living things
  • Botany: the study of plants, including agriculture
  • Cellular biology: the study of the basic cellular units of living things
  • Ecology: the study of how organisms interact with their environment
  • Evolutionary biology: the study of the origins and changes in the diversity of life over time
  • Genetics: the study of heredity
  • Molecular biology: the study of biological molecules
  • Physiology: the study of the functions of organisms and their parts
  • Zoology: the study of animals, including animal behavior

Developmental Biology has made substantial contributions to the field of Evolutionary Biology, providing tools that allow us to mechanistically study Darwin’s concept of “Descent with Modification”. This combination of Developmental and Evolutionary Biology has become its own discipline, Evo-Devo. The phenomena of heterotopy, heterochrony, and heterometry can combine in a variety of ways to bring about generational variation in a species that can, in conjunction with natural selection, result in evolutionary changes. “Darwin’s Finches” is an example of this. Provide...
