PLEASE HELP!! BIOLOGY
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?

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

The classical biological system of classification was developed by the Carolus Linnaeus in the 18th century which classified the organism into plants and animals like Aristotle.

After Linnaeus, the classification system has been changed to the three kingdom classification system by Haeckel in 1866, four kingdom classification system by Copeland in 1956, five Kingdom classification system by Whittaker and now six kingdom classification by Carl Woese in 1977. The six kingdom system is the modern system of classification which group organism into a larger group known as a domain.

This change in the system of classifying the organism indicates that the knowledge flourishes and diversifies with time which can change our understanding of nature like understanding of the living world. The advancement in our knowledge has helped shape the classification system.

Thus, option C is the correct answer.
