a great example is the peppered moth. look up the full story in wikipedia
the theory about how organisms change over time.
Survival of the fittest
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.
the evolution comes to the origin of species.
Darwinism is often what opponents to evolution call evolution to make it sound like some sort of Darwin cult, but it can also be used to just refer to evolution through natural selection as it was understood in the late 1800s, though that is usually called darwinian evolution rather than "darwinism". Also social darwinism is the application of natural selection to human civilization, the idea that the poor should starve to death because they're "weaker" etc. A faulty injection of biological science into social philosophy.

Natural Selection
Scientists use it to describe how organisms have changed over time.
The term that is often incorrectly used to describe evolution by natural selection is "survival of the fittest."
This is most commonly known as "selective breeding". It is also called "artificial selection" in an evolution sense.
the theory about how organisms change over time.
Survival of the fittest
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.
