Write a short essay (about 100-150 words) evaluating whether changes to an organism's physical environment are likely to result in evolutionary change. Use an example to support your reasoning.

Change in an organism's physical environment will cause the organism to adapt to fit in the surrounding environment. This process is called as adaptation. This process causes the evolution of the organism into a new species. The environment affects the evolution of the species, because change in environment put pressure on the species to adapt in change environmental conditions. Natural selection brings the change in the organism as the organism best suited for the environment survives. The example of evolution is the giraffe neck. Giraffe evolved by the development of tall neck slowly by increasing their neck length, so that they can eat leaf from the tall plants.
