Definition
Napak, East Africa, also Libya, Egypt, northern Kenya, southern Ethiopia
right before split of Colobinae and Cercopithecinae
shares bilophodont molars with cercopithecoidea
also ischial callosities |

Term
| Cercopithecoid/Hominoid Divergence |
|
Definition
older hominoids more diverse
perhaps result of climate change
cercopithecoids moved north, hominoids limited to forested areas
cercopithecoids more adapted terrestially |

but mix of quadrapedal and brachiating adaptations
what does this mean for locomotor evolution of pongo? |
