• Only on Earth, so far!

  Am organism is characterized as life by it's ability to reproduce, utilize genetic code for adaptation, metabolize, and maintain an internal environment. On Earth, life can be found nearly everywhere from deep beneath Antartica ice to hydrogen sulfide thermal vents at the bottom of the ocean. Life is single cellular, such as bacteria or basic algae, or multicellular, such as sunflowers, ants, termites, bats, and people.

  Conclusive evidence for life has currently only been found on Earth. Jupiter's moon, Europa, and Saturn's moon, Enceladus, are the current best candidates for life outside earth, due to their presence of water, oxygen, and geologic activity

  2. Single-celled: bacteria, simple algae, amoeba
  3. Multi-celled: flowering plants, dinosaurs, mammals, insects, primates
  4. There are over 5,000 species of bacteria living in the human gut, generally aiding in digestion
