• 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.
