No, baboons are not great apes. Baboons belong to the family Cercopithecidae, which includes Old World monkeys. Great apes, on the other hand, belong to the family Hominidae, which includes humans, chimpanzees, gorillas, and orangutans.
Baboons are primates, but they are more closely related to other monkeys than to great apes. They have tails, which great apes do not, and their body structure and behavior are quite different from those of great apes.
In summary, while baboons are fascinating primates, they are not classified as great apes. They are part of a different family and have distinct characteristics that set them apart from the great apes.
