How did carl woese discover archaea

Web19 de jul. de 2024 · The pioneering work of American microbiologist Carl Woese in the early 1970s has shown, however, that life on Earth has evolved along three lineages, now called domains—Bacteria, Archaea, and Eukarya. The first two are prokaryotic cells with microbes that lack membrane-enclosed nuclei and organelles. WebHe and his partners discovered the kingdom consisting of single-celled organisms, which is today referred to Archaea. Thanks to Woese’s discovery, we now classify living organisms in three domains, Archaea, Bacteria, and Eukarya. Before Woese’s breakthrough, we did not realize how common and important Archaea actually are.
