One great example of natural selection would be turtles. Most turtles have a smooth shell all the way, without many big bumps, but some turtles in a remote location were discovered to have a hump in their shells right where the turtle's neck was. Why did this happen? This was due to natural selection.
You see, the turtles that had a hump in their shell could reach much higher to get food, so they would be more likely to survive in a famine than normal turtles. The basic concept of evolution by natural selection is survival of the fittest.
Short form.
Natural selection is the nonrandom survival and reproductive success of randomly varying organisms.

Natural selection is only the result of changing environments, mutation and the variation resulting therein. Natural selection is the process of adaptive change and the main mechanism of evolution that leads to speciation. Natural selection is a process as mutation and variation are grist to the mill of natural selection.
Natural selection causes those organisms that are better suited to survive and reproduce to pass on their genes to future generations, causing their children to be better suited to their environment as well. Over time, these traits that have been selected by natural selection will result in an overall change in a species.
One was Darwin's theory was the process of evolution by natural selection and the second one was Lyell's theory was that animals can adapt and change their traits to fit the environment.
Selection is the process throughout evolution that results in a species existing in a current ecosystem at a given time. This is known as natural selection.
Natural selection is a mechanism of adaptive change in evolution.
The term that is often incorrectly used to describe evolution by natural selection is "survival of the fittest."

Evolution is a continuous, non-cyclical process that happens as long as there is life.

Graduated.
Natural selection means survival (and breeding) of the fittest, it is key to the evolutionary process.
Organic evolution is the process by which the genetic makeup of a species changes over time. There are several mechanisms by which this can happen: natural selection, genetic drift (chance), migration and mutation. So natural selection is one possible way in which evolution can take place. Most biologists agree that natural selection is the most important mechanism of evolution. This mechanism was first discovered by Charles Darwin and, independently. by Alfred Wallace.
