Word origin
The term "archaea" was coined by Carl Woese and George E. Fox in 1977 to describe a new domain of life. Archaea were initially classified as bacteria, but Woese's research on ribosomal RNA sequences revealed that they are genetically distinct. Archaea are now recognized as one of the three domains of life, along with bacteria and eukaryotes. They play a crucial role in various ecosystems and have unique metabolic pathways that have implications for biotechnology and astrobiology.
