The great apes are considered the smartest creatures after humans. Of course, humans are biased in this regard, but the intellectual capacity of the great apes is difficult to deny. After all, we share over 96 percent of the same DNA. Orangutans stand out as being especially gifted in the brains department.
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
Orangutans come in the first place here for a very interesting reason. Much like chimpanzees, the orangutan is able to use tools, learn sign language, and have complex social structures that involve rituals.
Combined with a powerful memory, these abilities make the chimpanzee the most intelligent (non-human) animal on Earth.
Humans have the highest EQ at 7.4, but bottlenose dolphins have EQs of 5.3, significantly higher than all other animals.
Chimpanzees. Chimps are our closest relatives in the animal kingdom, so it's unsurprising they display intelligence similar to that of humans. Chimps fashion spears and other tools, display a wide range of emotions, and recognize themselves in a mirror. Chimps can learn sign language to communicate with humans.
Dolphins are often cited as the second smartest animals on Earth due to their relatively high brain-to-body size ratio, the capacity to show emotion, and impressive mimicry of the dumb apes who research them.
According to several behavioral measures, Coren says dogs' mental abilities are close to a human child age 2 to 2.5 years. The intelligence of various types of dogs does differ and the dog's breed determines some of these differences, Coren says.
The domestic cat is attributed a value of between 1–1.71; relative to human value, that is 7.44–7.8. The largest brains in the family Felidae are those of the tigers in Java and Bali. It is debated whether there exists a causal relationship between brain size and intelligence in vertebrates.
Researchers have found that the average IQ of dogs is about 100. When compared to humans, this IQ is similar to the intelligence of two-year-old human toddlers. In general, studies have shown that canines have the smarts of children anywhere from 2 to 2.5 years of age.
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
New study suggests human brains are strongly shaped by external influences. Compared with most other animals, chimpanzees are incredibly intelligent: They work with tools, communicate with complex vocalizations, and are good problem-solvers. But as smart as chimps are, their brain power pales in comparison with our own ...
A variety of cognitive research on chimpanzees places their estimated IQ between 20 and 25, around the average for a human toddler whose brain is still developing the ability to use various cognitive abilities. This is not to say that chimpanzees are not intelligent animals.
A study from the University of Sydney and the University of Roehampton in London suggests that kangaroos are capable of intentionally communicating with humans, suggesting a higher level of cognitive function than previously thought.
Anecdotally, smarter people do seem to live longer. Isaac Newton died in 1727 aged 84, the philosopher-mathematician Bertrand Russell lived to 97, while Nobel Prize-winning neurobiologist Rita Levi-Montalcini died in 2012 aged 103.
Though this data might seem to suggest that dogs are twice as intelligent as cats, a direct correlation between larger brain size and increased intelligence has not been conclusively proven. Regardless, dogs' higher neuron count is often viewed as a gauge of their superior intelligence.
The IQ of an orangutan is 185 according to The Scale of Primate Intelligence. There are no tests devised that can test IQ in animals.
Albert Einstein likely never took an IQ test but is estimated to have a 160 IQ—but even that can't stand up to these masterminds.
The sperm whale has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms).
How About Whales? If you're asking yourself, “Are dolphins smarter than humans?”, they're not. Although dolphins and whales are extremely intelligent, they don't quite possess the prowess or intelligence that humans have.
