Transcript Homo sapiens

Apes
Orangutans
 Found in heavily forested
areas of Borneo and
Sumatra.
 Almost completely
arboreal.
 males = 200 lbs, females =
100 lbs
 Pronounced sexual
dimorphism.
 Solitary
 Principally FRUGIVOROUS
(fruit-eating).
Apes
Gibbons and Siamangs
 Found in the tropical areas of
southeast Asia.
 Adaptations for brachiation
may be related to feeding
while hanging from branches.
 Diet is largely fruit with
leaves, flowers, and insects.
 Basic social unit is a
monogamous pair and their
offspring.
 Males and females delineate
their territories with whoops
and “songs”.

Apes
Gorillas
• Largest of the living primates.
• Confined to forested regions
of central Africa.
• Males can weigh up to 400
pounds, females 200 pounds.
• Primarily terrestrial, using a
posture called “knuckle –
walking”.
• Groups consist of one large
silverback male, a few adult
females, and their subadult
offspring.
Apes
Chimpanzees
 Found in equatorial Africa.
 Anatomically similar to
gorillas particularly in limb
proportions and upper-body
shape.
 Locomotion includes knucklewalking on the ground and
brachiation in the trees.
 Eat a variety of plant and
animal foods.
 Large communities of as
many as 50 individuals.
Apes
Bonobos
 Only found in an area south
of the Zaire River.
 Population is believed to
only number a few thousand
individuals.
 Exploit the same foods as
chimps, including occasional
small mammals.
 Male-female bonds
constitute the societal core.
 Sexuality includes frequent
copulations throughout the
female's estrous cycle.
Apes
Humans (Homo sapiens)
 The only living
species in the family
Hominidae.
 Human teeth are
typical primate teeth.
 Dependence on
vision for orientation
to the world
 Flexible limbs and
grasping hands
 Omnivorous diet
 Cognitive abilities are
the result of dramatic
increases in brain
size.
 Bipedal
