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.
Unsurprisingly, chimpanzees are one of the most intelligent animals on this planet—next to humans, of course. Similar to how humans inherit their intelligence from their mother, a chimpanzee's intelligence also greatly relies on their genes.
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.
Bottlenose Dolphins
For years, dolphins have been heralded as the smartest animals on Earth, second only to humans—though some would even contest that ranking. Aside from humans, dolphins have the greatest brain-to-body ratio among animal species, including primates.
The human brain is about three times as big as the brain of our closest living relative, the chimpanzee. Moreover, a part of the brain called the cerebral cortex – which plays a key role in memory, attention, awareness and thought – contains twice as many cells in humans as the same region in chimpanzees.
Koalas have the smallest brains of any known mammals, and their behavior can be compared to someone who is high.
Scientists have studied both species and their brains to find the answer to this very question. And, scientifically speaking, dogs are likely smarter than cats. The research study looked at the brains of animals in the order Carnivora, a group of mammals containing bears, seals, raccoons as well as cats and dogs.
Koalas. Koalas are not only extremely cute, they're smart, too! The marsupials know how to listen to their bodies and can dive into a deep sleep for an average of 22 hours a day. Koalas snack on eucalyptus leaves, which aren't high in nutrients—the abundant rest makes this diet possible.
They learn faster than dogs or primates and their intelligence is compared to that of a three year old child. Cows have excellent problem solving skills that involve logic. Once they master how to solve a problem, they celebrate jumping, wagging their tails and running happily.
Within the encephalization quotient proposed by Jerison in 1973, values above one are classified big-brained, while values lower than one are small-brained. The domestic cat is attributed a value of between 1–1.71; relative to human value, that is 7.44–7.8.
The average dog's IQ is about 100. Based on the results done to test a dog's IQ, it turned out that dogs, even the average ones, have the IQ same as a 2-years old human.
Cats and dogs are colour blind
To see in full colour as we know it, humans use three cones – red, blue and green. However cats and dogs only have blue and green cones. This means they have a much more muted perception of colour, which is akin to colour blindness in humans.
To answer that question, yes kangaroos are very smart animals. When researched, they've shown intelligent behavior in many different scenarios. In a more recent study, researchers found that kangaroos displayed high levels of cognitive function through communicating with humans for food.
Horses are considered to be one of the most intelligent animals on Earth, due to their ability to learn quickly and remember things. They can also solve problems, figure out how to get something, and even understand human language.
Horses and Dogs are both intelligent animals, but they have different cognitive strengths. Horses excel in areas like navigational intelligence while dogs do better with social intelligence. Neither animal is smarter than the other, that's just what makes them unique!
Not only did the researchers discover that koalas are cleverer than first thought, but that these experimental structures are working to keep them safe.
Banana: more than 60 percent identical
Many of the “housekeeping” genes that are necessary for basic cellular function, such as for replicating DNA, controlling the cell cycle, and helping cells divide are shared between many plants (including bananas) and animals.
Friendliest Pet: Dogs
Dogs really are one of the best animals for humans. Loyal and sensitive to human emotions, dogs have gotten along with people throughout history.
Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
