Question

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?

Answer 1

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.

D, for sure
