Artificial Selection Answer Artificial Selection is the breeding of certain traits (better traits) over other traits. For example, breeding a good male horse with excellent racing qualities with a healthy female horse so that the offspring will have the desired traits such as the racing qualities. Another example is breeding good size fruits or vegetable together to keep on getting the good size.
Selection done by humans looking to maximize traits in animals under domestication. These traits are not always for the benefit of the organism though. Men raise these animals and mate the ones they think will breed true for a man favored trait and cull the rest of the organisms by killing them, or by not allowing them to breed.

Vestigial structures do not harm the organism. Nature selects against only harmful traits.

Random processes are not part of the theory of evolution by natural selection.
The sun is the source of energy that heats earth's surface. Radiation from the sun comes through the atmosphere, largely unhindered, and warms the surface of the earth.
