Quizplus · Accepted Answer

The commonly used microbial classification advancement that led to the tree by Carl Woese in 1977 was the 16S rRNA sequencing. This method involves comparing the sequence of a conserved ribosomal RNA gene present in all living organisms to determine evolutionary relationships between different microbial species. The resulting phylogenetic tree, also known as the three-domain system, classified organisms into three domains of life: Bacteria, Archaea, and Eukarya.
