Answer:

Homologies and vestigial structures  are two evidences of the evolution of how DNA and comparative anatomy used to show relatedness

Explanation:

Living organisms have characteristics that make them similar to others, which may suggest that at some point in the history of life on Earth, they shared a common ancestor. When we look at the limbs of a crocodile and a rat, for example, we find that, despite their differences in morphology, they are quite similar in anatomy, suggesting that they may be related. In this case, we say that the characteristic is homologous, that is, it has a similar embryonic origin, but it does not always perform the same function.

Trace structures are structures that are atrophied and have no apparent function in an organism. The presence of these organs can be interpreted as evidence of evolution, since the structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.
