The Sentient World of Animals
Animals Are
Intelligent Sentient Beings
By Hermitkid, Miaoli, Formosa (Originally in
Chinese)
It has been a common belief in our
society that fish are non-intelligent beings. This theory is rapidly
changing since new research shows that fish are actually socially intelligent
creatures that do not deserve the reputation of “dim-wits”
of the animal kingdom and instead they are cunning and even cultured.
Researchers from the Universities of
Edinburgh, St. Andrews and Leeds in the UK have gathered together powerful
evidence that puts a stop to the image of fish as “pea-brains”
with a “three-second” memory.
Scientists observed that fish recognized
individual “shoal mates” and respect the social prestige
of others. It has also been found that they use tools to build complex
nests and exhibit long-term memory.
In some areas of cognition, marine
animals are comparable to apes and monkeys, the most extraordinary example
being the dolphin. Acrobatic performances by a school of dolphins may
be widely perceived as a sequence of well-rehearsed actions. Certainly,
the dolphins may be following instructions, but they are able to spontaneously
accomplish the details of each action by themselves. They choreograph
their own dances. That is to say, the dolphins must communicate among
themselves in advance in order to put on a synchronized performance.
Animal intelligence may be measured by dividing the weight of the brain
by that of the body. The result places dolphins next to human beings
and much higher than non-human primates on this measuring scale.
A recent study by British scientists
showed that many animals are much more intelligent than previously imagined.
In a facial recognition test, a lamb was able to distinguish repeatedly
faces projected on a television screen. Studies also show that just
like chimpanzees, pigs can also control the joystick in front of a computer
screen. They can be trained to master action skills within shorter timeframes
than dogs require. Some pigs can serve as watchdogs, and some are even
capable of detecting landmines with their noses because they have a
highly developed smelling faculty. In some parts of France, farmers
rely on pigs to harvest truffles, a very expensive edible fungus that
grows underground.
British scientists also observed chickens
learning to adjust the temperature regulator in the barn. An American
scientist studying the social behavior of chickens found that a rooster
clucks to tell the hens that he has found food, and expresses his opinion
of it by uttering sounds of different pitches. When he sees food that
he likes, he bursts into a series of quick clucks and the hens gather
rapidly to enjoy it. However, if only ordinary feed is given, the rooster
issues slow clucks to indicate his disappointment, attracting only half
of the hens. Scientists studying birds also discovered that many of
them are very intelligent. Crows, for example, are very clever in their
reliance on human strength. For instance, they place nuts they cannot
crack on busy roadways, so that the traffic cracks the nuts for them.
Researchers noticed that a cow looks
very excited when it has learned new things. Experienced dairy farmers
also found that cows have color preferences. This animal is very similar
to humans in social behavior; they care about each other, and even raise
their young the way humans do. Calves, like human babies, act childishly
to attract the attention of their mothers.
According to Dr. Jane Goodall, who
is devoted to studying chimpanzees, intelligence assessments indicate
that livestock are smart animals, and therefore should not be consumed
by humans. When she realized this fact, she immediately stopped eating
meat, stressing that human beings should minimize their meat consumption.
