What is the LEAST useful indicator of an evolutionary relationship? ​
A)base sequence in DNA
B)amino acid sequence in a protein
C)similar ecological requirements
D)similar embryonic development
E)similar polypeptides

Quizplus · Accepted Answer

Similar ecological requirements can arise due to convergent evolution, where organisms develop similar characteristics due to similar environmental pressures, but not due to a common evolutionary ancestor. The other options, such as base sequence in DNA and amino acid sequence in a protein, are more reliable indicators for evolutionary relationships, as they directly indicate the genetic similarities between organisms.
