Question

1. how does artificial selection provide evidence for evolution by natural selection?

Explanation:

Artificial selection shows that humans can cause significant changes in species' traits over generations by choosing which individuals reproduce. This demonstrates that selection (even if human - directed) can lead to evolution. Natural selection works similarly, but with environmental factors (not human choice) determining which traits are favored. Since artificial selection can drive evolution, it implies that natural selection (which is a more widespread and long - term form of selection) can also cause evolutionary change.

Answer:

Artificial selection shows that selection (even human - driven) can cause evolutionary change. By analogy, natural selection (a more natural and long - term form of selection) can also drive evolution as it is based on similar principles of trait selection and inheritance.
