There are several evidences of evolution, some that we have greater knowledge and others we don't, but in this question all alternatives contain evidence of evolution, to understand better we need to know that.......
<h3>Fossil Evidence</h3>
Fossils are remains or traces of preserved organisms that are more than 10,000 years old and provide important information about life in past times and what the environment was like at a given time.
- Bones
- Teeth mark
- Footprints
- and petrified feces are examples of fossils.
<h3> Comparative embryology and Homologous structures</h3>
Some species have anatomical characteristics that are very similar to those present in individuals of other species. Although these structures often do not have the same function, it is possible to infer that, at some point, these species had a common ancestor.
<h3>Biochemistry and Metabolism</h3>
The analysis of cells and the biochemistry of organisms have revealed that there is much similarity between all living beings. This fact suggests that, at some point in evolutionary history, we had a common ancestor.
It can be seen, therefore, that the theory of evolution is supported by several pillars and every day it is more evident that living beings undergo changes over time.
With this information, we conclude that <u>all alternatives are evidence of evolution.</u>

Nucleic acids are the biopolymers, or large biomolecules, essential to all known forms of life. The term nucleic acid is the overall name for DNA and RNA . They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.
