The three-domain system sorts all life into Bacteria, Archaea, and Eukarya. Scientists proposed it based on new genetic evidence, shaking up the old kingdoms. Is it still correct? Mostly, yes—it's a strong foundation, but life is always revealing new, messy complexities at the edges. It reminds me of tracing a short circuit: the basic rules hold, but you always find one wire that doesn't follow the diagram, ayya.
