Which of these statements best explains how adaptation provides evidence to the scientific theory of evolution?

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 it survive better on earth.

The correct answer is option C.

Explanation:

The scientific theory of evolution was well explained by Charles Darwin when he published "On the origin of species" in 1859. He explained that species evolved when the species faced the pressure due to environment which leads to adaptation which resulted in survival. He called it survival of the fittest.

In evolution, the survival of the fittest due to adaptation has resulted in increasing the variations and complexity of the organism which is supported by the evidence collected by Darwin when he observed that Galapagos finches showed the  variations in the shape of the beaks due to different niches.

Thus, option C is the correct option .

age of consent is a crime, regardless of whether the other person actually is.
