Question

multiple choice 1 point
which of the following best illustrates how artificial selection demonstrates human influence on evolution?
humans selectively breed organisms with desirable traits, shaping species over generations
artificial selection eliminates the need for environmental adaptation in animals
artificial selection reduces biodiversity by preventing natural mutations from occurring
humans mimic natural selection by allowing only the fittest individuals to survive in nature

Explanation:

Artificial selection is when humans choose which organisms reproduce based on desirable traits. Over generations, this shapes species. For example, breeding dogs for specific looks or abilities.

• The second option is wrong because artificial - selected animals still need some environmental adaptation (e.g., domesticated animals still need basic care related to their environment).
• The third option is incorrect as artificial selection doesn't prevent natural mutations. It just selects among existing traits (and mutations can still occur).
• The fourth option is wrong because artificial selection is a human - driven process (e.g., in farms or breeding programs), not mimicking natural selection in the wild (where "survival of the fittest" is based on natural environmental factors, not human - defined desirability).

Answer:

Humans selectively breed organisms with desirable traits, shaping species over generations
