Bonobos,Chimpanzees,
Orangutans and Gorillas are our not so distant cousins in the animal world. They
are intelligent and exhibit feelings and emotions like we do. All
of these great apes are being threatened by deforestation and poaching. We must
take action to save this part of our "family" now. We are similar in many ways,
but for two, they can not "speak" and they do not destroy the
environment like we do.

The
Bonobo (Pan paniscus), sometimes called the Pygmy Chimpanzee, is one of the two
species comprising the genus Pan; both members of that genus are technically
"chimpanzees", though the term is frequently used to refer only to the
other member of the genus, Pan troglodytes, the Common Chimpanzee.
Bonobos
diverged from Common Chimpanzees after the last Common Chimpanzee ancestor
diverged from its last common ancestor with humans. Since no species other than
ourselves have survived from the human line of that branching, Bonobos and
Common Chimpanzees are our closest living relatives, sharing approximately 98.4%
of their DNA with us. They communicate through primarily vocal means, in a
language that has not yet been deciphered; however, we do understand some of
their natural hand gestures, such as their invitation to play. Bonobos are found
only in the Congo River basin of central Africa.
Size— Chimps and bonobos are about the same size, but bonobos are more
slender and have smaller heads and smaller ears. Food— Chimpanzees eat plant material as well as monkeys and other
mammals when they have the chance. Bonobos eat leaves, stems, fruits,
worms,insects, and sometimes small fish. Location— Bonobos are found only in a small part of one country in
Africa, the Democratic Republic of Congo (formerly Zaire). The four subspecies
of
“common” chimps range from western to central Africa. Getting Along— When trouble comes between common chimps, they often
fight it out. They are also very protective of their territory and will kill
chimps from another group, called a troop, if they try to move in. Bonobos
don’t seem to have established territories, and they tend to handle any
squabbles or tension by using different sexual behaviors instead of aggression. Looks— Bonobos can walk upright more easily than common chimps can.
They also keep their white rump patch for life, while the patch darkens with age
in chimps. And bonobos have hair on their head that parts right down the middle
Chimpanzees
just don't understand how humans can be so careless
Chimpanzees
Chimpanzees (Pan
troglodytes) are found in 21 African countries- from the west coast of the
continent to as far east as western Uganda, Rwanda, Burundi, and
Tanzania.
Chimps live in the greatest
concentrations in the rain forest areas on the equatorial forest
"belt."
Chimpanzees live in social groups called
communities. Chimps communicate with a
wide range of calls, postures and gestures.
There are four subspecies of
chimpanzees:
P.
troglodytes verus
Western
chimpanzee
P.
t. troglodytes
Central
chimpanzee
P.
t. schweinfurthi
Eastern
chimpanzee
P.t.
vellerosus

Nigerian - West Cameroon chimpanzee
Deforestation and commercial
hunting for bushmeat are taking a terrible toll on most chimpanzee
populations.
Orangutans
Orangutan
is pronounced orang-u-tan, as in suntan, not -tang. Orangutans are beautiful
red-haired mammals who live in the rain forests of Borneo and Sumatra in the
countries of Indonesia and Malaysia.In
Malay orang means "person" and utan is derived from hutan which
means "forest". Thus orangutan literally means, "Person of
the forest".
One
species with two subspecies, one from SUMATRA (Pongo pygmaeus abelii) and the
other from BORNEO (P. pygmaeus pygmaeus). The Borean male has large cheek pads,
a tremendous laryngeal sac and a square shaped face. The Sumatran male has small
pads and sac, a ginger colored mustache and a diamond shaped face. Individuals
can also be distinguished genetically (DNA sequencing) or chromosomally (karyotyping).
The
world’s population of wild orangutans is to be found exclusively concentrated
in the lush tropical rainforests of the islands of Borneo and Sumatra.
The
orangutan habitat has decreased by more than 80% in the last twenty years. The
areas most appealing to humans are often also those that are prime orangutan
habitat - lowland forests. Commercial ventures from timber and oil to rubber and
rice plantations destroy such vast tracts of land that orangutans are deprived
of even the minimum use of resources they need to survive.
Orangutans are classified as critically
endangered; in the wild they are estimated to number between 20-30,000.
Unless drastic measures are taken, orangutans will be extinct in the wild
within 20 years.

Gorillas
Gorillas,
previously considered a single species, were recently divided into two
species and five subspecies. The eastern gorilla (Gorilla beringei)
includes the mountain gorilla (Gorilla beringei beringei) of the
Virunga Volcanoes area of Rwanda, Uganda and the Democratic Republic of
Congo, the yet unnamed, but distinct, population of Uganda's Bwindi
(Impenetrable) Forest, and the eastern lowland gorilla (Gorilla
beringei graueri). Western Africa is home to at least two additional
taxa, the western lowland gorilla (Gorilla gorilla gorilla) and the
Cross River gorilla (Gorilla gorilla diehli). The mountain, Bwindi
and Cross River gorilla populations all number only in the hundreds and
are considered critically endangered.

POPULATION/DISTRIBUTION
Western
-
Approximately 10,000-35,000
free-living, 550 in captivity worldwide. Found in Nigeria, Cameroon,
Gabon, Congo, Central African Republic and Zaire.
Eastern -
Approximately 4,000
free-living. Less than 24 in captivity. Found in eastern Zaire.
Mountain -
Approximately 620
free-living. Zero in captivity. Found in 285 square miles in the rain
forests of Rwanda, Uganda and Zaire.
Gorillas
are primarily vegetarians, and large quantities of food are needed to
sustain their massive bulk. The gorilla has 48 chromosomes, like the
chimpanzee, bonobo, and orangutan, with a very similar banding pattern to
the 46 chromosomes of humans
Koko
signing "Help"
Koko
, a gorilla, has a working vocabulary of over 500 signs and has emitted
over 400 more. Koko understands approximately 2,000 words of spoken
English. Koko initiates the majority of conversations with her human
companions and typically constructs statements averaging three to six
words. Koko has a tested IQ of between 70 and 95 on a human scale, where
100 is considered "normal."
