Question

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

Explanation:

Artificial selection is when humans choose which organisms reproduce based on desired traits. This is different from natural selection (where nature decides). Let's analyze each option:

• "Humans mimic natural selection by allowing only the fittest individuals to survive in nature": In artificial selection, humans act on domesticated or controlled - environment organisms, not in "nature" in the sense of wild ecosystems. Natural selection acts on wild populations based on environmental pressures.
• "Artificial selection eliminates the need for environmental adaptation in animals": Artificial - selected animals still need to adapt to their (human - controlled) environments. For example, a prized show dog still needs to adapt to its living conditions like shelter and diet.
• "Artificial selection reduces biodiversity by preventing natural mutations from occurring": Artificial selection doesn't prevent mutations. Mutations are random genetic changes. Breeders may select against some mutations but can't stop them from happening.
• "Humans selectively breed organisms with desirable traits, shaping species over generations": This is the core of artificial selection. For example, breeding cattle for more milk production or dogs for specific physical and temperamental traits.

Answer:

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