The length of the intestine determines intelligence?

Experimental, it is confirmed between intellectual development, brain size and length of the intestine having mutual relationships.

Scientists believe that intelligence depends on the size of the brain: the brain gets bigger and smarter. Of course, the connections between neurons also play an important role, but the key factor that primate species is superior to other animals is the ratio between the brain and their bodies is higher. both.

Usually the advantage is to pay, but the price here is the fertility and size of the intestine. This means that the bigger the brain, the shorter the length of the intestine and the more fertile it is. The intestine, as well as the female, consumes a lot of energy and the volume of the brain increases, there is no energy left for it. So for the big brain to have to 'sacrifice' the length of the intestine.

But more and more, these assertions are gradually hypothetical and are no longer supported by experimentation and are considered to be rules.

Intelligence is determined by the length of the intestine.

Since the 19th century, it has been proved that animals with large brains will survive in harsh conditions. For example, American biologist Hermon Bumpus has commented that species that are big brains will tolerate winter more easily.

Contemporary biologists have acknowledged this idea after determining that the big brain helps birds adapt to life in the city, while small brain birds live only in the countryside.

Studies by Swedish experts from Upsala University can be considered revolutionary. They experiment with the purpose of examining the two hypotheses: About the rise of intelligence and the price to pay for an animal to have a big brain.

The object to be tested is a guppy fish. Scientists have chosen their own fry based on the largest and smallest brain size for generations. As a result, they obtained two 'fish' that differ in size of the brain by 8% in males and 10% in females.

The researchers then examined whether the difference in brain size of the two 'lines' could lead to differences.

They show giant fish paintings of two or four symbols. One of those 4 paintings draws a dish. The big brain fish understands quickly the difference between the two drawings, but the small brains cannot teach them to distinguish this simple thing.

Thus, scientists have shown that intelligence indeed depends on the size of the brain. At the same time they also proved that 'stupid' fishes are always more fertile. They average 7 children while the average 'smart' fish has 6 children. Correspondingly, the gut of small brain fish weighs 5.5mg and big brain fish is only 4mg.
