The correct answer is: Our current system consists of 3 domains, and it has changed as new information is uncovered.
Explanation: The current biological classification system includes three domains: Archaea, Bacteria, and Eukarya. This system was developed because advances in molecular biology, particularly DNA sequencing, have revealed significant genetic differences between organisms that were previously classified together. As new information has been gained about these organisms, the classification system has evolved to reflect a more accurate understanding of the relationships among them.
