The best piece of evidence to support the conclusion that the two species are closely related is:
**A DNA analysis shows that these species share 97% of their DNA.**
This high percentage of shared DNA indicates a significant genetic similarity, suggesting a close evolutionary relationship between the two species. While other pieces of evidence (like embryological analysis and shared anatomical features in fossils) can also suggest relatedness, DNA analysis provides a more objective and quantifiable measure of genetic similarity.
