Humans have the ability to learn, to reason, and to solve problems on our own. We can express our thoughts and feelings through different mediums. We can also process ideas, from simple to the complex ones while understanding what those meant. While scientists do not agree with the best definition of intelligence, they agreed that these traits that humans possess are signs of intelligence.
However, humans are not the only ones who exhibit signs of intelligence. Previous studies showed that animals are also smart in ways that we didn't expect. Let's get to know some of these animals.

1 - Chimpanzees
Chimpanzees are known to possess almost the same intelligence as humans. It was found out that our genomes are at least 99 percent identical. A 2007 study gave adult chimps, adolescent chimps, and college students the same cognitive test to identify their brainpower. According to an article by Popular Science, an American quarterly magazine carrying popular science content, the researchers reported that both chimps and humans saw the same numbers in their locations for less than a second.

2 - Dolphins
Studies showed that dolphins have among the largest brains in the animal kingdom when it comes to body mass to brain ratio. They are known to have advanced communication skills and can recognize themselves in a mirror. Also, dolphins are using distinct whistles and clicks that may serve as their names. According to scientists, this is a sign of intelligence.

3 - Elephants
Elephants have larger brains compared to other animals. With that, there is no doubt that they can create and process complex social interactions. They can even model human traits such as empathy. According to an article by NBC News, the news division of the American broadcast television network NBC, elephants can do a lot of things such as communicate with one another using vibrations sensed in their feet, help other species in times of need, and many more.

4 - Octopuses
According to scientists, most invertebrates don't have that much intelligence. However, octopuses are different. They can distinguish between two different people, considered as highly skilled hunters, and have the ability to solve some very complicated problems.

5 - Crows
Some of you might be surprised to know that crows could be smart as people, or perhaps even smarter. According to an article by List25, an online site that compiles lesser-known intriguing information on a variety of subjects, crows are among the most intelligent birds in the world. They can adapt to a tough situation and solve complicated problems. Ravens, a type of crow, are known to manipulate the consequences of their social interactions to gain more food and for added protection.

6 - Dogs
Widely known as the "man's best friend," dogs are an all-time favorite pet. They learn new skills easily and are quick to respond to human training, which is why humans are fond of them. Previous studies suggested that at least find food in response to non-verbal cues. Some breeds of dogs like Poodles, Border Collies, and Labrador Retrievers are very curious about their environment. They can even notice a change in the smallest detail.

7 - Cats
Just like dogs, cats are one of the easiest pets to train. They can learn to jump through hoops, rollover, and sit down. Cats can learn tricks and techniques through imitation and observation. However, experts said that they are harder to teach than dogs. This is because they are naturally motivated by the need to survive. This has allowed them to adapt to a variety of domestic environments for a long time.
