It proves that natural selection is the only means of evolution.
It shows that organisms choose to adapt to changing Earth conditions.
It proves that natural selection leads to greater complexity in organisms.
It shows that some features in an organism help it survive better on Earth.

Adaptation provides evidence to the scientific theory of evolution as It proves that natural selection leads to greater complexity in organisms.

Explanation:

The basic tenets of the theory of evolution were the survival of the fittest and the theory of natural selection which postulated that what is fit for the environment it lives in survives into the next generation.

The proof of adaptation made this theory seem viable by proving that it is indeed through natural selection that organisms in evolve into the better more complex versions of themselves in the times of peril and the organism's genetic makeup slowly changes with this process.
