Similarities across 200 genes related to hearing and deafness that were discovered in new research have yielded proof of echolocation capabilities in cetaceans, including dolphins, that were evolving independently of but convergent with the sonar hearing capabilities for which bats are well known.
[A] that were discovered in new research have yielded proof of echolocation capabilities in cetaceans, including dolphins, that were evolving independently of but
[B] that were discovered in new research yields proof of echolocation capabilities in cetaceans, including dolphins, that were evolving independently of but also
[C] having been discovered in new research have yielded proof of echolocation capabilities in cetaceans, including dolphins, that were evolving independently of but
[D] discovered in new research yields proof of echolocation capabilities in cetaceans, including dolphins, evolving independently but also
[E] discovered in new research have yielded proof of echolocation capabilities in cetaceans, including dolphins, that evolved independently of but

First of all, let's get rid the choices with the singular verb 'yields' as 'similarities' requires a plural verb. B and D are gone.
Then drop C for distorting meaning by using the present perfect progressive -having been' as if because the similarities were discovered they have yielded proof.
Between A and E, the trick is to fix the correct tense of the verb; A simple past tense is required to describe something that happened in the past; -were developing -- is inappropriate. Hence E
One must be careful while fixing the modifiers with their relevant nouns.

[A] that were discovered in new research have yielded proof of echolocation capabilities in cetaceans, including dolphins, that were evolving independently of but - Incorrect. 'that' must refer to 'similarities' and not 'deafness'.
[B] that were discovered in new research yields proof of echolocation capabilities in cetaceans, including dolphins, that were evolving independently of but also - Incorrect. Same error as in A.
[C] having been discovered in new research have yielded proof of echolocation capabilities in cetaceans, including dolphins, that were evolving independently of but - Incorrect. Awkward.
[D] discovered in new research yields proof of echolocation capabilities in cetaceans, including dolphins, evolving independently but also - Incorrect. Subject verb agreement error.
[E] discovered in new research have yielded proof of echolocation capabilities in cetaceans, including dolphins, that evolved independently of but - Correct
