Question

which best describes the relationship between evolution and natural selection?
○ natural selection leads to evolution.
○ evolution leads to natural selection.
○ natural selection is the same as evolution.
○ evolution and natural selection are not related.

Explanation:

To determine the relationship between evolution and natural selection:

• Natural selection is a mechanism (process) that drives evolution. Evolution is the change in species over time, and natural selection acts on heritable traits, favoring those that increase survival/reproduction, which leads to evolutionary changes in populations.
• Option 1: "Natural selection leads to evolution" is correct because natural selection is one of the main causes of evolution.
• Option 2: Evolution does not lead to natural selection; natural selection is a process that contributes to evolution.
• Option 3: Natural selection and evolution are not the same—natural selection is a mechanism, evolution is the result of such mechanisms (and others like genetic drift, mutation, gene flow).
• Option 4: They are related, as natural selection is a key driver of evolution.

Answer:

A. Natural selection leads to evolution. (Assuming the first option is labeled A; adjust label based on original, but the correct statement is "Natural selection leads to evolution".)
