- More about Carl Woese
- What are archaea?
- He is a scientist who classified organisms into three categories: archaea, eukaryotes, and bacteria. (https://en.m.wikipedia.org/wiki/Three-domain_system)
- What are eukaryotes (eukarya)?
- He was a microbiologist who revolutionized the field of phylogenic taxonomy. The tree of life orginally included two domains, prokaryotic and eukaryotic, until Woese disproved this hypothesis through the use of ribosomal RNA (rRNA). (https://www.nasonline.org/member-directory/deceased-members)
- What are bacteria?
- Archaea are a group of micro-organisms that are similar to, but evolutionarily distinct from bacteria. They usually thrive in extreme environments, for example at high pressures. (https://microbiologysociety.org/why-microbiology-matters/what-is-microbiology/archaea)
- Was his classification accepted back then?
- Is it valid?
- Bacteria are small single-celled organisms. Bacteria are found almost everywhere on Earth and are vital to the planet's ecosystems. (https://www.genome.gov/genetics-glossary/Bacteria)

- It was quite a slow process. Promiment biologists objected to his division of the prokaryotes. Though, not all criticism of him was restricted to the scientific level. Then, the growing amount of supporting data led the scientific community to accept the Archaea by the mid-1980s.
