Question

Quizplus · Accepted Answer

Molecular evidence, particularly the analysis of ribosomal RNA sequences, showed that prokaryotes are divided into two fundamentally different groups, leading to the establishment of the domains Bacteria and Archaea. This was a significant revision of the tree of life, recognizing the deep evolutionary divide between these two groups.
