Which two scientists developed the three domain system?

The three-domain system was developed by Carl Woese, a microbiologist, and his colleagues Otto Kandler and Mark Wheelis. In 1990, they proposed this system based on their analysis of ribosomal RNA (rRNA) sequences, which revealed fundamental differences between prokaryotic groups, leading to the classification of life into three distinct domains: Archaea, Bacteria, and Eukarya.
