Complete Question:

In the 18th century, Carolus Linnaeus classified organisms based on their structural similarities.

Modern classification determines relationships more accurately because it is based on genetic

and other biochemical similarities. This change in classification method best illustrates that:

(1) multiple trials are required to increase the validity of a scientific explanation

(2) scientific explanations are subject to the ethical view of the scientist proposing them

(3) peer review is required to validate the results of scientific investigations

(4) all scientific explanations are tentative and subject to change and improvement

(4) all scientific explanations are tentative and subject to change and improvement

Explanation:

Carolus Linnaeus was a scientists who created a means,system, method or way by which living organisms where organised and classified based on certain and similar structural features or characteristics which these organisms possessed.

The classification system Carolus Linnaeus created was referred to as Taxonomy. Hence, Carolus Linnaeus was called the Father of Taxonomy. This classification system followed an Order of hierarchy.

Modern classification classifies living organisms and determines their relationship with one another based more accurately on genetic and other biochemical similarities.

This change that is observed in method of classifying living organisms best illustrates and shows us that all scientific explanations are tentative and subject to change and improvement.
