Sagot :

Final answer:

DNA serves as evidence for evolution through shared genetic codes among different species.


Explanation:

The use of DNA as evidence for evolution:

  • Genetic Code: All organisms share a similar genetic code composed of DNA sequences that code for proteins.
  • Common Ancestry: Similarities in DNA sequences among different species indicate a common evolutionary origin.
  • Universal Genetic Code: Virtually all species use the same genetic code for protein synthesis, supporting the idea of a shared ancestry.
