Studies from biochemistry provide evidence of the evolutionary relationships between primates. It was found that the sequence of haemoglobin in gorillas differs by one amino add from haemoglobin in chimpanzees and humans, whose sequence is the same. Models were constructed showing the possible relationships between humans, chimpanzees and gorillas. Which model best represents the relationship according to haemoglobin structure?
