According to previous research, the average IQ level of Chimpanzees is between 20 and 25 which is equal to a human toddler. Their IQ is of toddlers but they exhibit incredible problem-solving skills which has been confirmed by several experiments. Moreover, studies have shown that Chimpanzees are self-aware and can recognize themselves in mirrors just like humans.

They have surprised many researchers with their cognitive abilities. Chimpanzees are born with complex social skills and some are learned from the environment including cooperation, rectification, duplicity, and tactical deception.

What Does IQ in Animals Represent?

Like humans, animals have brains and process different situations differently depending upon their abilities. The Intelligence Quotient or IQ is a parameter used to measure intelligence. It is basically designed for humans but now it is being used on several animals to see what animal has the highest and what has the lowest IQ.

Animals do not show intelligence like humans. Therefore, researchers use various scales to measure the intelligence of animals to rank them as the most intelligent or least intelligent in the animal kingdom. These include attention, cognitive bias, language, memory, time perception, spatial cognition, and others.

Which animal has the highest IQ?

Chimpanzees are considered the most intelligent species out of all animals after human beings. They understand complex situations intelligently. Moreover, they share 98.8% DNA similarity with humans.

What is the less intelligent animal?

Koalas are one of the most less intelligent animals as compared to others. They live a very simple life and their needs are very limited. One of the major reasons for their minimalist approach to life and behavior is that they have no advanced cognitive abilities to process their surroundings.

Ranking animals based on their IQ level is difficult because there are multiple scales by which the intelligence of an organism is determined. It varies from one species to another depending on how they process things and how they use their cognitive abilities. Through research and previous data, we found Chimpanzees are the most intelligent and the ability of sloths to process different matter is the slowest which is why they are the least intelligent and have the lowest IQ.
