Biology – The natural science that involves the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy.

Branches of biology[edit]

Branch of biology – subdiscipline of biology, also referred to as a biological science. Note that biology and all of its branches are also life sciences.

  • Anatomy – study of form in animals, plants and other organisms, or specifically in humans. Simply, the study of internal structure of living organisms.
  • Astrobiology – study of origin, early-evolution, distribution, and future of life in the universe. Also known as exobiology,and bioastronomy.
  • Bioengineering – study of biology through the means of engineering with an emphasis on applied knowledge and especially related to biotechnology.
  • Bioinformatics – use of information technology for the study, collection, and storage of genomic and other biological data.
  • Biomechanics – the study of the mechanics of living beings.
  • Biochemistry – study of the chemical reactions required for life to exist and function, usually a focus on the cellular level.
  • Biogeography – study of the distribution of species spatially and temporally.
  • Biophysics – study of biological processes through the methods traditionally used in the physical sciences.
  • Biotechnology – new and sometimes controversial branch of biology that studies the manipulation of living matter, including genetic modification and synthetic biology.
    • Synthetic biology – research integrating biology and engineering; construction of biological functions not found in nature.
  • Botany – study of plants.
  • Cell biology – study of the cell as a complete unit, and the molecular and chemical interactions that occur within a living cell.
  • Cognitive biology – study of cognition.
  • Comparative anatomy – the study of evolution of species through similarities and differences in their anatomy.
  • Chronobiology – field of biology that examines periodic (cyclic) phenomena in living organisms and their adaptation to solar- and lunar-related rhythms.
  • Cryobiology – study of the effects of lower than normally preferred temperatures on living beings.
  • Developmental biology – study of the processes through which an organism forms, from zygote to full structure
    • Embryology – study of the development of embryo (from fecundation to birth).
    • Gerontology – study of aging processes.
  • Ecology – study of the interactions of living organisms with one another and with the non-living elements of their environment.
  • Epidemiology – major component of public health research, studying factors affecting the health of populations.
  • Evolutionary biology – study of the origin and descent of species over time.
    • Evolutionary developmental biology – field of biology that compares the developmental processes of different organisms to determine the ancestral relationship between them, and to discover how developmental processes evolved.
    • Paleobiology – discipline which combines the methods and findings of the natural science biology with the methods and findings of the earth science paleontology.
      • Paleontology – study of fossils and sometimes geographic evidence of prehistoric life.
  • Genetics – study of genes and heredity.
  • Marine biology – study of ocean ecosystems, plants, animals, and other living beings.
  • Microbiology – study of microscopic organisms (microorganisms) and their interactions with other living things.
  • Molecular biology – study of biology and biological functions at the molecular level, with some cross over from biochemistry.
  • Neuroscience – study of the nervous system, including anatomy, physiology and emergent proprieties.
  • Oncology – study of cancer processes, including virus or mutation, oncogenesis, angiogenesis and tissues remoldings.
  • Photobiology – scientific study of the interactions of light (technically, non-ionizing radiation) and living organisms. The field includes the study of photosynthesis, photomorphogenesis, visual processing, circadian rhythms, bioluminescence, and ultraviolet radiation effects.
  • Physiology – study of the internal workings of organisms.
  • Population biology – study of groups of conspecific organisms.
  • Parasitology – study of parasites and parasitism.
  • Psychobiology – study of the biological bases of psychology.
  • Radiobiology – study of the action of ionizing radiation on living things.
  • Sociobiology – study of the biological bases of sociology.
  • Structural biology – a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules.
  • Theoretical Biology – the mathematical modeling of biological phenomena.
  • Systems biology – computational modeling of biological systems.
  • Zoology – study of animals, including classification, physiology, development, and behavior. Subbranches include:
    • Arthropodology – biological discipline concerned with the study of arthropods, a phylum of animals that include the insects, arachnids, crustaceans and others that are characterized by the possession of jointed limbs.
      • Acarology – study of the taxon of arachnids that contains mites and ticks.
      • Arachnology – scientific study of spiders and related animals such as scorpions, pseudoscorpions, harvestmen, collectively called arachnids.
      • Entomology – study of insects.
      • Carcinology – study of crustaceans.
      • Myriapodology – study of centipedes, millipedes, and other myriapods.
    • Ethology – scientific and objective study of animal behaviour, usually with a focus on behaviour under natural conditions.
    • Helminthology – study of worms, especially parasitic worms.
    • Herpetology – study of amphibians (including frogs, toads, salamanders, newts, and gymnophiona) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras).
      • Batrachology – subdiscipline of herpetology concerned with the study of amphibians alone.
    • Ichthyology – study of fishes. This includes bony fishes (Osteichthyes), cartilaginous fishes (Chondrichthyes), and jawless fishes (Agnatha).
    • Malacology – branch of invertebrate zoology which deals with the study of the Mollusca (mollusks or molluscs), the second-largest phylum of animals in terms of described species after the arthropods.
    • Mammalogy – study of mammals, a class of vertebrates with characteristics such as homeothermic metabolism, fur, four-chambered hearts, and complex nervous systems. Mammalogy has also been known as "mastology," "theriology," and "therology." There are about 4,200 different species of animals which are considered mammals.
      • Cetology – branch of marine mammal science that studies the approximately eighty species of whales, dolphins, and porpoise in the scientific order Cetacea.
      • Physical anthropology – studies the physical development of the human species.
      • Primatology – scientific study of primates
    • Nematology – scientific discipline concerned with the study of nematodes, or roundworms.
    • Ornithology – scientific study of birds.
