Final answer:
The amino acid sequences of human and bonobo hemoglobin are almost identical, suggesting a more recent common ancestor, while their differences from the sequence of wolf hemoglobin indicate a more distant common ancestor.
Step-by-step explanation:
The fact that the amino acid sequences of human and bonobo hemoglobin are almost identical, yet they differ considerably from the sequence of the hemoglobin of wolves, indicates that these species have different evolutionary histories. The similarities in the amino acid sequences between humans and bonobos suggest a more recent common ancestor for these species, while the differences between humans/bonobos and wolves indicate a more distant common ancestor. These comparisons reveal insights into the evolutionary relationships between different species.
