On the basis of similar body structures scientists hypothesize the two species are closely related what other evidence would the scientist look forward to support their hypothesis?

To support their hypothesis of close relatedness between the two species, scientists would examine genetic evidence, such as DNA sequences, to identify similarities and differences in their genomes. They might also analyze protein structures and biochemical pathways, as well as fossil records that indicate shared evolutionary history. Additionally, behavioral and ecological similarities could provide further support for their relationship.
