Primates spearing primates
It’s no big deal

A lesser galago or bushbaby
A small population of Savannah chimps (Pan troglodytes verus) living in
the Fongoli area of Senegal has been observed using sticks as spears to hunt bushbabies
(Galago senegalensis—a small, cute, wide-eyed, animal with prominent
ears).1 Chimps have long been known
to fashion simple twigs for ant dipping and termite fishing, but these chimps sharpened
sticks with their teeth to better spear the smaller primates. Using a ‘power
grip’, the chimps attempted to stab the bushbabies inside hollow trunks and
branches.
This observed behavior has created an evolutionary frenzy. A New Scientist article
states, ‘In a revelation that destroys yet another cherished notion of human
uniqueness, wild chimpanzees have been seen hunting bushbabies with spears.’1
Jill Pruetz, a primatologist at Iowa State University, said ‘Back to the drawing
board again in terms of trying to define how humans are special.’ However,
a closer look at the evidence reveals a story that is far less sensational.
Tool use in the animal world
Several other animals are capable of using tools as well
Chimps are intelligent and resourceful animals. The Fongoli chimps, in particular,
display an impressive resourcefulness and sense of planning by utilizing sharpened
sticks as spear-like objects to hunt bushbabies. However, several other animals
are capable of using tools as well. For example, New Caledonian crows design and
manufacture different types of sticks to probe for insects.2 Like the Fongoli chimps, woodpecker finches break
off sharp pieces of cacti to spear insects.3
Egyptian vultures are famous for launching stones in order to break open ostrich
eggs.3 Dolphins affix sponges to their snouts and stir up the sea floor
to hunt fish.4 Elephants trim twigs
and branches to create the perfect design for swatting flies and scratching themselves.5 In short, a number of animals are
capable of making and using crude tools. God has endowed many animals with the intellectual
capacity to solve problems, fashion crude tools, and plan for the future.
Statistics, natural selection, and intellect
Sxc.hu, Chad Littlejohn
Chimpanzees have been observed hunting bushbabies with spears.
One little detail that is easily overlooked is that the Fongoli chimps were successful
in killing the bushbabies in only 1 out of 22 recorded attempts.6 This is a paltry 4.5% success rate. Pruetz said,
‘Still, this involves significantly less energy than in chasing down monkeys,
so it is not surprising that it evolved.’ The problem is that such a high
rate of failure would hardly suffice in providing sufficient nourishment for a primate
the size of a chimpanzee. An animal can conserve all the energy it wants in developing
more advanced tools, but if it yields a poor success rate the animal will eventually
die. Therefore, the more simple method of chasing down and beating monkeys to death
is actually more intelligent, since it yields a higher rate of success. As a result,
natural selection would tend to select against any subhuman, ape-like hominid struggling
to develop more advanced hunting tools.
In addition, in the evolutionary model, chimpanzees have supposedly existed for
about six million years. Apparently, they have survived quite well by expending
large amounts of energy in chasing down monkeys at times. Also, if in six million
years chimpanzees have only now figured out how to use a stick as a makeshift spear,
it does not speak very well of their intellectual ability. Human beings possess
the intellectual capacity to rapidly develop new forms of technology in vastly shorter
periods of time. There is really no comparison between human and chimpanzee mental
abilities.
Conclusions
The evolutionary community sees two major implications in this story about the Fongoli
chimps. First, human beings are not unique in the animal world. This is strictly
a philosophical worldview. Second, human tool use evolved step-by-step from a common
ancestor shared with chimpanzees. This is pure speculation seen through the lens
of Darwinian evolution. Observational evidence reveals that chimps, like many other
animals, can be highly resourceful in using simple tools to hunt prey and perform
basic tasks. It does not constitute any evidence that chimpanzees evolved from a
creature that in the past was not a chimpanzee. Nor does it constitute any evidence
that mankind developed its tool use capability from an animal ancestor in the distant
past. It simply and only demonstrates what chimps can do.
The Bible makes it clear that chimpanzees and humans were created as distinct kinds.
And human beings were specially created in the image of God with an intellectual,
technological, moral, and spiritual capacity far more advanced than any chimpanzee.
