The acts of cannibalism and infanticide are very apparent in the behavior of the chimpanzee.
Many African studies show that wild chimpanzees kill and eat infants of their own species. This essay will deal with chimpanzee aggression, cannibalism and infanticide. This paper will present information on major research studies performed in Africa and analyze how and why this strange behavior occurs in a commonly thought peaceful primate.
Wild chimpanzees Pan troglodytes schweinfurthii are known to kill and eat mammals in various parts of Africa.
Moreover, there is new evidence that chimpanzees near the Ugalla River of western Tanzania also consume mammals. The Chimpanzee society is clearly a male dominated aggressive social unit. Males are larger than females, they are more openly aggressive, and they fight more often.
But it is rare For a fight between community members to last Longer than quarter of a minute, and it is Even more unusual for such a fight to result In serious injury.
Afterwards the loser of the fight, even though clearly fearful of the aggressor, will almost always approach him and adopt a submissive posture. Although females sometimes display this behavior, especially high ranking, confident females, it is typically a male performance. The chimps hair then begins to bristle and his lips bunch in a ferocious scowl.
He may pitch rocks or jump around swinging branches. The rewards of the alpha male are claiming rights to the food, female partners, and he also acquires a position exempt from attack by fellow chimps.
A chimpanzee community has a home range within which its members constantly roam. Usually the home range consists of roughly five to eight square miles.
The adult male chimpanzees usually in groups of three, take turns patrolling the boundaries of their area keeping close together, silent and alert. If a patrol meets up with a group from another community, both sides usually engage in threats, and then are likely to retreat back to their home ground.
They hit, kicked, and bit him for twenty minutes and left him bleeding from many serious wounds. A month later after this original occurrence another prime Kahama male was caught by three chimps from Kasakela and severely beaten. A few weeks later he was found, terribly thin and with a deep unhealed gash in his thigh.
There were three more brutal attacks leaving three more Kahama chimpanzees dead before Gilka ran screaming but Passion who was bigger and stronger caught up, attacked, seized, and killed the baby.
She then proceeded to eat the flesh of the infant and share the gruesome remains with her adolescent daughter, Pom and her infant son, Prof. This was the first observed instance of cannibalistic behavior shown by Passion and Pom. There is no explanation why Passion and Pom behaved as they did.
It was only as Pom grew older That the very close bond developed between Mother and daughter, and it was only because The two acted with such perfect co-operation That they were able to overcome some of the Other females of their community. Instead they would wait for the mother to be alone with her infant and gang up on her.
In three years from to only a single infant in the Kasakela community had lived for more than one month. Finally, when Passion gave birth again to a third child, and Pom also gave birth, the extraordinary cannibalistic infant killing came to an end. The study group, M-group, consisting of about 90 chimpanzees, has been monitored for 15 years.
During a chimpanzee group feeding period that had gone unsuccessfully. Kalunde a 2nd-ranking male walked up to and snatched a six-month old infant baby boy from the hands of its mother Mirinda. Kalunde ran with the infant on his belly with Mirinda chasing after him screaming.
Kalunde then hid in some vegetation until two other males Shike and Lukaja found him and wanted to take the infant away from him.
Lukaja finally won a tug of war for the infant between the two other males and handed it over to Ntologi the alpha male. Ntologi, who then dragged, tossed, and slapped it against the ground climbed a tree with the infant in his mouth.
He waved it in the air, and finally killed it by biting it on the face. Then he proceeded to eat the infant sharing the meat with the other chimps.
Unfortunately, in this case though, it was the meat of a dead chimpanzee infant. Nevertheless, after the infanticide, Mirinda was observed to mate with Ntologi as well as Kalunde.Primatologist Jane Goodall was the first to observe this infamous female behavior in in a cannibalistic mother-daughter duo, the chimpanzees being named Passion and Pom.
