What do you call a physician? a doctor that only treat 1 species. Ha! This joke informs the divide between human doctors and doctors that treat animals aka veterinarians.
Natterson-Horowitz and Bowers suggest we have a lot of scientific/biological information we can learn from the veterinarians. Monkeys also suffer cardiac arrest, octopi and stallions also self-mutilate. If we know how to treat these problems in animals, surely some of this knowledge can be transferred to human patients. It appears that dinosaurs got brain cancer, so knowing that cancer has been around for so long may shed light on what causes and how to treat diseases like cancer.
