Does the brain size affect intelligence?

The question of whether brain size affects intelligence is strongly discussed in science and there is no certainty about this matter. There is evidence that suggests that brain size can change, but there is also evidence that suggests that this is not the most important factor. According to some experts, the size of the brain seems to be more important to some intelligence than others. There are studies in the Kingdom of Animals that have also shown great contradictions of brain size and intelligence between different species, and this generally made scientists more uncertain about the problem.

Animals that have made scientists more insecure are birds. Many species of birds, especially those in the Crow family, show very complicated social behavior and show the ability to think. In general, despite the fact that their brains are less than many species with less impressive cognitive abilities. Some experts think that this is because birds habty complex neural structures that allow more efficient moschEC.

There are also other studies that show a strong direct relationship between brain size and intelligence. These studies examined intelligence tests in a number of species and focused on a more general type of problem solving. The reason for these results is questionable. Some experts believe that it is simply physically causing animals for some reason to require greater intelligence, while others think that brain size is the primary factor.

In humans, studies of brain size and intelligence were also relatively contradictory. For example, most men have larger brains than most women, but the studies were unable to find statistically significant differences in intelligence between men and women. There are many cases where people with much smaller brains have demonstrated much more mental capacity than people with a larger brain. In general, the size of the brain and the body size are usually proportionally related betweenHuman, but intelligence and body size are often completely unrelated.

Some experts think that the brain structure, or perhaps the specific size of certain parts of the brain, have more in common with intelligence. There is also evidence that changes in brain size based on human experience and as people gain more mental knowledge, their brains can actually grow. There is a lot of evidence that would suggest that this happens in the childhood when people evolve, but there are also evidence that shows that this happens after people have achieved adulthood.
