In the image, we have the skeletons of a gibbon, a human, a chimpanzee, a gorilla, and an orangutan.
All of these organisms are primates and are somewhat similar, for example:
-All of them are capable of having an upright position, as we see in the image.
-None of them have tails.
-Their bone structure is very similar.
But also they have several differences:
-All of them, except humans, have arms that are longer than their legs.
-The non-humans have smaller skulls.
-The gibbon and the human have smaller mandibles and pelves than the others.
