Carl R. Woese (microbiologist)

Carl R. Woese was a pioneering microbiologist who revolutionized our understanding of life's classification. He used genetic analysis, specifically comparing the sequences of ribosomal RNA, to identify fundamental differences among microorganisms. His work led to the recognition of a new domain called Archaea, distinct from bacteria and eukaryotes (plants, animals, fungi). This redefined the tree of life, highlighting evolutionary relationships. Woese’s discoveries provided a deeper understanding of microbial diversity and evolution, impacting biology, medicine, and ecology. His contributions are foundational in modern microbiology and biological classification systems.
