Darwin proposed that natural selection could be an explanation for the origin of all living things by natural cause.

Explanation:

Darwin proposed that natural selection could account for what he saw as the tree of life. Darwin believed that all living things were related to each other, through modification of existing organisms.

He observed that organisms produces many more offspring that could survive.
He observed that there were variations in the offspring.
He observed that some offspring were better adapted to survive in the environment than others.
He proposed that natural selection would select the best adapted variations.
He believed that there were potentially infinite variations that could account for life starting as a single cell and resulting in the present complexity of modern organisms.

Darwin proposed his theory of evolution based on natural selection and the assumption of infinite variations in living things. (Note the assumption of infinite varieties has been called in to serious questions by what is now known about DNA.)
