Question

the classification system for organisms has changed from seven levels to eight. this happened because scientific consensus changed as scientists learned more about organisms. scientists did not test the seven - level system often enough to lead to consensus. the eight - level system of classification is an emerging idea that needs more testing. the seven - level system of classification was not supported by scientists.
