  • Living things are sorted into three domains: Bacteria, Archaea and Eukarya.
  • Eukarya includes protists, fungi, plants and animals, and those kingdoms are still revised as new evidence appears.
  • Archaea are prokaryotes, and many live in extreme conditions.
  • Each species has a two-word scientific name, written with a capital letter only on the genus.
