why do classification systems change over time?\no scientists find new evidence in their studies.\no scientists use old methods of classification.\no scientists repeat experiments and find no changes.\no scientists find similar evidence to previous work.
Answer
Brief Explanations:
Classification systems are based on evidence. New evidence from scientific studies can lead to re - evaluation and change of these systems. Old methods, lack of new findings (repeating experiments with no changes or finding similar evidence) do not cause change.
Answer:
Scientists find new evidence in their studies.
