All 29 monkeys adapted to the direct strategy quickly, compared to a measly 39% of humans. The results of the study put capuchin monkeys and rhesus macaques at the same level as chimpanzees and baboons with regards to better mental ability to adapt to new rules compared to humans.

Monkeys and apes who incorporated animal proteins into their diets also had slightly larger brains than the leaf eaters, the Nature Ecology and Evolution study found. Previous studies have shown that larger groups of primates with more complex social structures are correlated with larger brains.

It was proposed that relatively larger primate brains were supported by their using relatively bigger proportions of the available energy pool (Armstrong, 1983a). Different primates, however, are also thought to differ in relative brain size. Pro- simians have smaller brains for their body sizes than do monkeys.

In primates, for example, the brains of apes are generally larger relative to body weight than the brains of monkeys, whereas the brains of monkeys are larger than those of prosimians (2). Increases in the size of primate brains have come despite the fact that brain tissue is metabolically very costly (7).

Monkey brains are not only smaller than human brains, but also differ in their internal connections. The same holds true for mouse brains, which deviate greatly in the most ancient and basic areas of the brain. Neuroscientist Rogier Mars compared the human brain with that of macaques, chimpanzees and mice.

Christopher Michael Langan (born March 25, 1952) is an American horse rancher and autodidact who has been reported to score very highly on IQ tests. Langan’s IQ was estimated on ABC’s 20/20 to be between 195 and 210, and in 1999 he was described by some journalists as “the smartest man in America” or “in the world”.

Benjamin Netanyahu is alleged to have an IQ of 180.

A score of 116 or more is considered above average. A score of 130 or higher signals a high IQ. Membership in Mensa, the High IQ society, includes people who score in the top 2 percent, which is usually 132 or higher.

The highest average score for people under 64 years of age is attained by those people between the ages of 55 and 64, who get 109 on the IQ scale. People between 65 and 69 years of age have an average IQ score of 114, which puts them in the superior intelligence or above-average end of the scale.

IQ classification is the practice by IQ test publishers of labeling IQ score ranges with category names such as “superior” or “average”….Historical IQ classification tables.

between 160 and 180

By adding to that storehouse, reading increases your crystallised intelligence. In fact, the increased emphasis on critical reading and writing skills in schools may partly explain why students perform, on average, about 20 points higher on IQ tests than in the early 20th century.

For college age and 60-74 year olds, accuracy on both of the recognition tests increased significantly with IQ. But for the 75-90 year old participants, it did not; performance for most of the 75-90 year olds was close to floor. For all three groups, there were modest increases with IQ for cued and free recall.

Give your brain a daily workout to sharpen your focus and become more intelligent.

1. Follow ideas through to various outcomes.
2. Add 10-20 minutes of aerobic exercise to your day.
3. Engage in stimulating conversation.
4. Take online courses.
5. Give your brain a break.
6. Practice a hobby.
7. Look, Listen, Learn.

Foods linked to better brainpower

• Green, leafy vegetables. Leafy greens such as kale, spinach, collards, and broccoli are rich in brain-healthy nutrients like vitamin K, lutein, folate, and beta carotene.
• Fatty fish.
• Berries.
• Tea and coffee.
• Walnuts.

9 Ways to Instantly Strengthen Your Brain

1. Exploit your weakness. This first challenge will seem counterintuitive, but there’s good science to support it.
2. Play memory games.
3. Use mnemonics.
4. Raise your eyebrows.
5. Read books that push your boundaries.
6. Try new hobbies.
7. Eat better.
8. Exercise.

Aerobic exercise, like running and swimming, appears to be best for brain health. That’s because it increases a person’s heart rate, “which means the body pumps more blood to the brain,” says Okonkwo. But strength training, like weight lifting, may also bring benefits to the brain by increasing heart rate.
