In the early 1700s linnaeus came up with a new system of classification of living things that eventually replaced the one that had been used since aristotle developed it in ancient greece about 2000 years earlier. why was a change necessary?
a new system was needed to include the new species that had evolved since the original classification system was developed.
so many new species were being discovered, it was impossible to arrange them all in a hierarchy based on relative complexity of species.

The correct answer will be option- so many new species were being discovered, it was impossible to arrange them all in a hierarchy based on relative complexity of species.

Explanation:

The history of classifying the organisms started in 360 B.C when Aristotle made an attempt to classify the organisms into two groups- plants and animals.  

After Aristotle attempts by Theophastrus and many others were made but it was in 1735 when a classical system was developed by the taxonomist Carolus Linnaeus which classified the organism in two groups like Aristotle-the plants and animals.

In the course of 2000 years between Aristotle and Linnaeus, the system changed a lot due to advancement in the science as well as the large and wide approach (complexity) to classify the organism and new species discovered between this period which had to be fitted in the system. This led to the evolution of a new system to classify the organisms.

Thus, the selected option is the correct answer.
