The best piece of evidence that would support the conclusion that the two species are closely related is:
**A DNA analysis shows that these species share 97% of their DNA.**
This is because DNA comparison provides a direct molecular measure of genetic similarity, indicating a close evolutionary relationship. The higher the percentage of shared DNA, the closer the species are likely to be in terms of their evolutionary lineage.
