When the Linnaean system of classification was first developed in the early 1700s, it only had two kingdoms for living things, the plant and animal kingdoms. Three more kingdoms have been added since then, as well as a higher division of three domains. Why are we still using this system if we have to keep changing the way it is organized?

Question

anonymous · Answer

A. Each change represents new species that have evolved since the system was developed. 
B. It has been used for so long that it would be difficult to change to a different one. 
C. The changes reflect increases in our knowledge of the structure and operation of living things. 
D. The general system still works despite all the changes each generation of scientists has added.

I'm not 100% sure on the answer (as I am not so familar with the topic) but D seems to be a reasonable choice. If scientists haven't changed the system, it must still work or else they wouldn't be able to use it.
