Final answer:
Classification systems are human inventions used to understand the diversity of life on Earth, which is the product of evolution.
Step-by-step explanation:
The statement means that classification systems, created by humans, are used to organize and understand the vast diversity of life on Earth. These systems, such as the Linnaean classification system, categorize organisms based on their similarities in physical traits. On the other hand, diversity itself is the result of evolution, a natural process driven by mutations and natural selection that allow organisms to adapt to changing environments. Evolution leads to the development of new species and the branching out of different groups of organisms over time.
