1977 Carl Woese and George Fox publish a paper in PNAS identifying the third domain of life, the archaebacteria (now commonly called Archaea).
Biologists now argue the case for either five (monera, protista, plantae, fungi, animalia) or six kingdoms (plants, animals, protists, fungi, archaebacteria and eubacteria).
Computer analyses of complete genomes suggest that some archaebacteria employ both eukaryotic and eubacterial mechanisms in translation initiation.
