Apes and Humans
Homonoids
Complex Behavior
Special, Unique, deception ability.
No external tail
larger in body size
dental differences between hominids and pongids
Pongid means homiNOIds
Hominids
Completely terrestrial
Canines minimally dimorphic
Relative to molars canines are small and non-projecting
lack of diastema
parabolic dental arcade
relatively featurelesss molars and premolars
The more arboreal an ape is, the less important the thumb is
this can tell you how an animal moves in the trees
Orangutans
located in Borneo and Sumatra
Pronounced sexual dimorphism
Males
so big that they cannot usually move through trees
solitary with occasional contact.
Females
almost completely arboreal
usually not "solitary." Carrys an immature offspring for most of life
Gorillas
largest primate
located in equatorial Africa
sexual dimorphism
teeth
head
males terrestrial
groups consist of one silverback male, a number of females; and offspring
will tolerate other males
vegetarian
Homonoids/Pongids
Canine are sexually dimorphic in pongids
Canine relative to molar are large and projecting
Diastema btween canines and incisors
