What is the change over time through natural selection?
The change over time through natural selection refers to the genetic changes in a species offspring and how those different genotypes react with the environment. For example, many years ago in Europe there was a coal plant that caught fire and exploded. Coal was everywhere for a very long time and it turned the city black. Because of this, the areas population of yellow butterflies began to disappear since the birds could very easily see the bright yellow color over the black coal. Eventually, a population of black butterflies began to appear out of what seemed to be nowhere, but what really happened is that somewhere down the line of those butterflies a black one was born. After the event of the factory explosion when everything had turned black, and the yellow butterflies began to die off, the black species began to flourish because they were able to survive in their new environment. This is what happens with natural selection.
