Pongid

Not to be confused with Ponginae

Pongid refers to members of the obsolete taxon Pongidae. They are sometimes called great apes.[1] Pongidae is now known to be paraphyletic. Pongids gave rise to hominins around seven mya.[2] The corresponding crown group for this taxon is Hominidae. Pongidae has six extant member species. This taxon is rarely used today but is of historical significance.

Distinction to hominins[edit]

Average brain capacity400 cc1700 cc
Skull (viewed from top)pear-shapedovoid
Widest part of skull viewed from behindParietal regionBase of the skull(near the auditory region)
PalateRectangularParabolic
Body GrowthFastSlow

Skull[edit]

The pongid skull contains the following features that are absent or less pronounced in humans:

Adaptations for locomotion[edit]

The following adaptations are for arboreal and knuckle walking locomotion and are not found in humans:

PongidHuman
Arms are as long as or longer than the legsArms are shorter than the legs
Scapula has an orientation for supporting the body weight beneath the armsScapula is oriented for holding the arms by the side
Digits are long and curved for grasping branchesDigits are shorter and straight
Pelvis is shaped to support the legs and trunk in the bent-over posturePelvis is shaped to support the legs and trunk in a vertical position
Knees do not lock the legsKnees lock the legs straight to minimize the expenditure of energy when standing
Pelvis is relatively largePelvis is much shorter and bowl-shaped
Iliac pillar is elongatedThe iliac crest is oriented more to the side and slanted

Similarity to hominins[edit]

The australopithecines show intermediate character states between pongids and humans, with Pithecanthropus intermediate between australopithecines and humans. Members of the genus Homo share many key features with anatomically modern man.
