Which of the following best explains how artificial selection provides evidence for evolution by natural selection?
A
Artificial selection indicates that environmental factors have no impact on species development.
B
Artificial selection shows that all traits in organisms are inherited without variation.
C
Artificial selection proves that natural selection does not occur in nature.
D
Artificial selection demonstrates that selective pressures can lead to changes in species over time.
Verified step by step guidance1
Understand the concept of artificial selection: Artificial selection is a process where humans selectively breed organisms to enhance or modify specific traits. This is similar to natural selection, where environmental pressures lead to changes in species over time.
Compare artificial selection to natural selection: In natural selection, environmental factors determine which traits are advantageous, leading to changes in species. In artificial selection, humans determine which traits are desirable, but the underlying mechanism of selection is similar.
Identify the role of selective pressures: Both artificial and natural selection involve selective pressures that influence which traits become more common in a population. In artificial selection, these pressures are human-imposed, while in natural selection, they are environmental.
Recognize the evidence for evolution: Artificial selection provides evidence for evolution by demonstrating that selective pressures, whether natural or artificial, can lead to changes in species over time. This supports the idea that natural selection can drive evolutionary change.
Conclude with the correct explanation: The correct explanation is that artificial selection demonstrates that selective pressures can lead to changes in species over time, providing evidence for the process of evolution by natural selection.
