The piece of evidence that would best 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 genetic similarities are one of the strongest indicators of evolutionary relationships, as they reflect common ancestry. The higher the percentage of shared DNA, the more closely related the species are likely to be.
