*It was identified in the bonobo monkey DNA that there is
only 1.3% of differences with humans.

future, set goals and follow their progress
WASHINGTON, USA (29/JUN/2012.) - The more we study animals;
we are less human than them.
Baboons can distinguish between real and false words. The
monkeys seem to be able to multiply. Apes can delay instant gratification for
longer than a child and can plan ahead. They are also able to make war and
peace, empathy and sharing.
"It's not a question of whether or not they think. Is
how they think," says scientist Brian Hare at Duke University. Now
scientists wonder whether monkeys are capable of thinking about what others
think of apes.
Evidences that animals are smarter and more social than
we thought seem to increase every year, especially the primates of the world.
It is a field of science which is increasingly sought.
The number of studies of cognition between apes and monkeys doubled in recent
years, often through better technology and neuroscience, which pave the way for
unusual discoveries. This month, scientists mapped the DNA of bonobo ape
discovered that, like the chimpanzee, has only a 1.3% difference with humans.
"Every year we discover things we thought could not
be," says Josep Call, director of the Primate Research Center of the Max
Planck Institute in Germany.
Call says one of his most striking recent studies showed
that monkeys can set goals in their world and track progress.
In a zoo, scientists offered eight possible tools to
orangutans and bonobos, two of which could help them get food. Sometimes when I
chose the right tool, the researchers moved to a different area before they
could get food, and then kept on hold until 14 hours.
In almost all cases, when the monkeys realized they were
being moved, they took the tool so it can be used to get food the next day,
even remembering to take it after sleep. Apes do not forget your goal or series
of steps.
Call says this is like what a person to pack their
luggage one day before traveling: "For humans it is very important core
skill."
In recent years, scientists have observed how chimpanzees
in zoos stones collected and stored for use later as weapons. In May, a new
study found that even make use of deception. Chimpanzees created a haystack to
hide caches of stones from their rivals, just as nations do with bombs.
Hare says there are studies in chimpanzees carried rivals
a place where some food hidden from view, except from one monkey. The chimp can
see the hidden food, quickly realizes that his enemy can not see and use that
in your favor, demonstrating the ability to perceive the situation of another
monkey.
That's a trait that humans developed from being young
children, but it's something we thought we were not able to do other animals,
said Hare. Then there is the incredible memory of monkeys.
According to French research, at least two baboons
continued to memorize as many pictures "several thousand" that after
three years the researchers ran out of time before the baboons reached their
limit. The researcher Joel Fagot, National Research Center Scientifique in
France believe they are able to memorize at least 10 000 photos and probably
more.
A chimpanzee in Japan, named Ayumu, who see series of
numbers flashing on a screen for a split second defeat humans regularly
doubling the number accurately. The video is a YouTube sensation, along with
the Miami Zoo orangutans using iPads.
Not only primates show amazing abilities. The dolphins,
whose brains are 25% heavier than humans, are recognized in a mirror, like
elephants. A study in June concluded that black bears can rely on a primitive,
something that even the pigeons have been made in an experiment by putting two
points before five, or 10 before 20.
The trend of research is to identify some new thinking
skills that chimpanzees can do, revealing that certain skills are not
"uniquely human," the primatologist Frans de Waal of Emory
University. Then scientists discovered that same ability in other primates
genetically distant from humans. Then find it in dogs and elephants.
At Duke, Professor Elizabeth Brannon shows videos of
monkeys that appear to be doing a "fuzzy representation" of
multiplication, tracking the number of points that go to a box on a computer
screen and select the correct response of the total. This is after they already
made additions and subtractions.
During the second quarter, in France, the researchers
showed that six baboons could distinguish between real and fake words of four
letters: CASA and BRRU, for example. They also sought to make their computer
exercises at will, either for fun or for a snack.
It was once thought that the skills to manage emotions,
empathize and socialize separated us from our primate cousins, but chimpanzees
are comforted and fight. They also try to calm an upset partner.
When scientists study another of our closest relatives,
the bonobo, they found one important
difference: Bonobos do not kill. Hare says his experiments show that bonobos
offer food to the newcomer bonobos, even when they might prefer to stay with
all the food.
Yet there are limits on what you can do non-human
primates. Animals, for example, lack the ability to communicate with the
complexity of human language.
In the French study, baboons can recognize the letters
form a word HOUSE true because after trial and error, learning the letters tend
to go together in some order. However, baboons have no idea what it means to
CASA. That emptiness is the key. "The boundaries are not as sharp as
people think, but there are certain things that can not be overcome and language
is one of them," said Herbert Terrace, animal cognition researcher at
Columbia University.
And that brings us to another difference, Ross said.
Because the apes have no language skills, only learn by watching and imitating.
Humans teach the language and explanation, which is faster and better, he
added.
