Barbara Inman Pd.1 Take Home Test   Adaptation—any variation that makes an organism better suited to its environment. A variation is a difference in an individual that makes them different from other members in their species. Adaptations make an organism capable for them to live effectively in their environment. An adaptation can change the looks of an organism or its behavior. An example of an adaptation is when an organism changes its color to hide better in its environment.

 Organisms must adapt to their environment so that they are able to survive. If they do not adapt, they will either have to move out of their environment or they will die.     Natural selection is the process by which the traits better suited to an organism’s environment become more frequent, while the unfavorable traits become less frequent. It was introduced by Charles Darwin in his 1859 book, //On the Origin of Species//. “[The] principle by which each slight variation, if useful, is preserved,” is how Darwin explained natural selection. There are five principles of natural selection. These include, organisms produce more offspring than can survive, differences occur among individuals of a species, and some variations are passed to offspring. The last two are some variations are helpful, individuals with helpful variations survive and reproduce better than those without these variations, and over time, the offspring of individuals with helpful variations make up more of a population and eventually may become a separate species.
