Answer: C
Explanation: DNA evidence supports the theory of evolution primarily because of the genetic similarities found among different species. The statement that best explains why DNA evidence can support the theory of evolution is:
C. All living organisms have genetic similarities due to similar habits.
1. DNA evidence allows scientists to compare the genetic information of different organisms.
2. Similar genetic sequences in DNA indicate a common ancestry between species.
3. These genetic similarities can be attributed to the evolutionary process where organisms with common ancestors share genetic traits.
4. Organisms with similar habits may have evolved similar genetic adaptations, leading to genetic similarities despite their differences in appearance or behavior.
5. Therefore, genetic similarities in DNA provide strong evidence for the theory of evolution and the idea of a common ancestor for all living organisms.
