Document Summary
After split of platyrrhine and catarrhines: saadanius. Bony ear tube = more derived than aegyptopithecus. Earliest old world monkeys: molecular divergence estimate for split between cercopithecoids and hominoids = 9 kg: victoriapithecines = early miocene of north and east africa. Ate hard fruit and seeds (microwear with pitting) Greater tubercle height above articular surface = terrestrial. Smaller than all other macaques = dwarf macaque . Extinct forms all in europe as early as 10,000 years ago. Mangabeys = arboreal group (lophocebus) and terrestrial group (cercocebus) Used to think baboons and mandrills were sister taxa; geladas on their own; mangabeys one group. Mandrills and terrestrial mangabeys are each other"s closest. Savannah baboons and mandrills were not sister taxa. Arboreal and terrestrial mangabeys were not sister taxa. Baboons and arboreal mangabeys are each other"s closest relatives. Morphologists tended not to believe molecular folks since similarities are so striking but there was no behavioral data to support.
