One of the mysteries of the English language finally explained.
Microorganisms that are similar to bacteria in size and simplicity of structure but radically different in molecular organization. They are now believed to constitute an ancient intermediate group between the bacteria and eukaryotes.Also called archaea

- ‘They conjecture that an evolutionary quantum leap happened after an archaebacterium swallowed a eubacterium.’
- ‘These sequences included proteins from a diverse range of organisms, ranging from eubacteria and archaebacteria to algae, fungi, and plants.’
