Final answer:
The difference of one amino acid in the hemoglobin sequence between humans and gorillas indicates they are closely related and have a recent common ancestor, rather than humans evolving from gorillas or being the same species.
Step-by-step explanation:
Humans and gorillas having one different amino acid in their hemoglobin sequence suggests that they are closely related species. This single amino acid difference indicates that humans and gorillas share a considerable amount of genetic material, likely because they have a recent common ancestor. However, it does not imply that humans evolved from gorillas or that they are the same species. Instead, the evidence from amino acid and DNA sequence comparisons among different species, including chimpanzees and humans, supports the idea that these species have diverged from a common ancestor through the process of evolution. As species evolve separately, some of their genetic sequences can change, resulting in differences like the one observed in hemoglobin between humans and gorillas.
