To answer this question, let's look at the Peruvians in the Andes. Due to the high altitude, they have developed bigger lungs due to thinner air and shorter limbs for blood flow. This is a perfect example of how animals, especially humans, can adapt to changing climates over a large period of time.
Evolution is a change in species over time.
Species not always change over time such sponges :D
Evolution is the change in species over long periods of time.
A gradual change in life-forms over time is organic evolution.
Adaptation is when a species is able to change over time to new changes in their environment.
Evolution
It's Evolution

If there was no change in species over time, then all fossils of that species would be identical.
