The lines of evidence that support the theory of evolution by natural selection include the comparison of body structures in modern organisms, the comparison of DNA sequences in different organisms, and the study of the geographic distribution of species on Earth (all of the above are lines of evidence that support the theory of evolution).
The theory of evolution by natural selection is a well-sustained scientific model proposed by Darwin that states species change (evolve) as a consequence of the process of natural selection, which can be defined as the differential survival and reproduction of the more adaptive organism in a given environment.
Therefore, with this data, we can see that the theory of evolution by natural selection states that organisms better adapted to environmental conditions have more chances of surviving and reproducing.
