Quizplus · Accepted Answer

The similarity in amino acid sequences of hemoglobin between humans and chimpanzees, compared to the considerable differences with dogs, supports the theory of evolution. It suggests a closer evolutionary relationship between humans and chimpanzees, indicating that they share a more recent common ancestor than either does with dogs. This pattern of similarity and difference aligns with evolutionary predictions about common ancestry and divergence.
