Explain how goal of today’s classification system differs from earlier systems
gladu [14]

Classification systems previously were having very different goals than modern classification systems. If we look at old eras, scientists like Aristotle  and Theophrastus  tried to classify organisms on the basis of apparent characteristics, habitat and simple other traits.

Old classification systems had alot of errors and flaws. For example they classified fish and whale in one group because they lived in water, now we know fish is amphibian while whale is mammal.

So we can say that the goal o earlier classification system were just to make groups of organisms on the basis of External features.

Goal of modern classification system:

Modern classification approach was started by Linnaeus. It focuses more on biological delimitation and evolutionary histories than mere external characteristics. It organizes organisms in groups in such a way that grouping reflects their evolutionary relatedness. It is not just specie level but also focuses on sub-specie and population level classification.


Thus modern goal is better in many terms and is more reliable than old classification goals.
