The document discusses research into whether animals other than humans can develop sickle cell anemia. Hemoglobin B sequences were analyzed from various primates and other organisms. Phylogenetic trees showed chimpanzees and orangutans were most closely related to humans. However, the research did not find any evidence that mutations in hemoglobin B led to sickle cell anemia in other organisms, contrary to the initial hypothesis. Further research may be needed to fully examine if other primates could genetically acquire sickle cell anemia.
