Final answer:
Classification systems in biology change due to new evidence and advancements in research methods.
Explanation:
Why do classification systems change over time?
Classification systems in biology change over time primarily because scientists find new evidence in their studies. With advancements in technology and research methods, new species are discovered, and genetic analysis often reveals discrepancies in earlier classifications. For example, as scientists uncover additional information through genetic studies, they may need to revise phylogenetic trees to reflect more accurate evolutionary relationships.
