 | | Histological studies of the teeth of Dryopithecus and Sivapithecus suggest that these creatures grew fairly slowly, as living great apes do, and that they probably had life histories similar to those of the great apes - maturing at a leisurely rate, living long lives, bearing one large offspring at a time, and so forth. |
 | | We lack direct clues to brain size in Sivapithecus, but given that life history correlates strongly with brain size, it is likely that this ape was similarly brainy. |
 | | Most important, both Dryopithecus and Sivapithecus display adaptations to suspensory locomotion, especially in the elbow joint, which was fully extendable and stable throughout the full range of motion. |
