Although dogs may be better at helping people, cats have much more sophisticated brains. Dogs only have 160 neurons in their brains compared to cats' 300 neurons, making them one of the smartest animals in the World.
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.
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.
#3: Chimpanzees
Chimpanzees are very smart animals and are able to solve many different problems posed to them by human trainers and experimenters. Our closest genetic relative comes in third place on this list of the most intelligent animals.
Pigs are gentle creatures with surprising intelligence. Studies have found they're smarter than dogs and even 3-year-old children! In the wild, pigs form small groups that typically include a few sows and their piglets.
Humans have the highest EQ at 7.4, but bottlenose dolphins have EQs of 5.3, significantly higher than all other animals.
First up, unsurprisingly, is cetaceans - or for the purpose of this article, dolphins and whales. These creatures are supremely intelligent, with some scientists arguing that they are the most intelligent creatures on our planet.
There are several possible answers to this question as different animals display varying levels of intelligence. However, some experts suggest that the animal with the lowest IQ is the sloth.
Some researchers say pigs are even smarter than 3-year-old human children! Pet pigs can learn lots of circus tricks. They can learn how to find food using a mirror and even how to play video games using a joystick! Check out this video of a pet pig performing tricks!
Dogs score higher in perceived intelligence ratings than cows, for example, yet a study in the 1970s demonstrated that in a test cows could navigate a maze as well as dogs, and only slightly less well than children. The point was made that our perception of an animal's ability is influenced by how we test them.
Did you know that pigs are considered the 4th most intelligent animal (after chimpanzees, dolphins and elephants).
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.
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.
1. Border collie. According to The Intelligence of Dogs, which ranks 131 dog breeds in terms of their relative intelligence, the border collie is the smartest dog breed known to man.
1. Border Collie: A workaholic, this breed is the world's premier sheep herder, prized for its intelligence, extraordinary instinct, and working ability. 2. Poodle: Exceptionally smart and active.
Elephants Elephants have an imposing physical presence and exude calm and confidence in everything they do. They have an extremely kind and spiritual demeanour and are incredibly intellectual. In fact, African Elephants are amongst the world's most intelligent species.
Three-toed sloths are some of the slowest and seemingly laziest creatures in the world. Instead of evolving to eat more, they evolved to do less.
The great apes are considered to be the smartest creatures after humans. Among them, orangutans stand out as being especially gifted with brain. They have a strong culture and system of communication, and many have been observed to use their tools in forest.
IQ tests are made to have an average score of 100. Psychologists revise the test every few years in order to maintain 100 as the average. Most people (about 68 percent) have an IQ between 85 and 115. Only a small fraction of people have a very low IQ (below 70) or a very high IQ (above 130).
The intelligence quotient (IQ) is a measure of a person's thinking capacity. In a nutshell, it is meant to assess how well someone can utilize facts and reasoning to answer questions or make predictions. Short- and long-term memory is measured in IQ tests to begin to examine this.
The sperm whale has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms).
Through his systematic analysis, Coren found that dogs have specific types of intelligence seen in no other animals except humans. In meaningful ways, dogs are smarter than our closest primate cousins: the bonobos, orangutans, and chimpanzees.
Dogs, it turns out, have about twice the number of neurons in their cerebral cortexes than what cats have, which suggests they could be about twice as intelligent.
