Charles Darwin noticed that among the same species there were variations in traits based upon geographical location. These changes may have evolved from climate differences, predator/prey relationships and food sources. This particular experiment was intended to duplicate natural selection by demonstrating the concepts with artificial selection. The result was that over time, new traits could be bred for. Although there may be more than one correct answer here, the best answer is the first; desirable traits can be selected and bred in offspring.

Children will have different tones or shades of skin from their parents due to human skin colour having multiple genes. This is an example of polygenic inheritance.
Explanation:
see the picture below to see how different skin colours depend on where they live:
