Is intelligence due to genetics?

Each person is born with wisdom and over time, it is improved through experience and understanding. But if we were born with superior intelligence available, would that be due to inheritance from genetic factors?

Over the years, scientific research has tried to discover how and why some people are smarter than others. They also tried to find out, everyone's intelligence (or ability to solve problems) was equally "heavenly" when they were born, then gradually improved over time, the growth Is the superiority or intelligence inherited from the gene? Will the geniuses of humanity inherit genetic genes from previous generations?

In fact, the variability of the intelligence is quite large.There are dozens or hundreds of genes that affect the intelligence of each of us. This is also what makes scientists difficult to prove the hypothesis of a particular gene that contributes to improving our IQ.

Of course, scientists still get the answer. Recently, American and British scientists have concluded the largest genetic research conclusion in finding that particular gene. More than 200 researchers compared the existence of a mutation, that is, a change in the regulation of HMGA2 gene , in more than 21,000 patients and compared it to the size of the brain parts. of each person.

The discovery that this gene was previously only involved in human height had a change in its DNA along with the exchange of a molecule replaced by thymine and cytosine. This mutation causes the brain to be larger than 3cm ³ and the results of these IQ tests are 1.29 points higher than the average person. If both parents have the same mutation, their child's IQ will increase by 2.6 points.

This result does not seem to be very noticeable because the change is too small and the researchers cannot prove whether there is a more developed area in the brain than elsewhere. But it is the first discovery directly related to a single gene affecting human intelligence.

Are political options also affected by genetics? The Political Physiological Laboratory of the University of Nebraska - Lincoln collaborated with political scientist John Hibbing to confirm a series of studies that are at least related to physical, our brains are shape from birth to being a liberal or conservative thinker.

Everyone's intelligence is not the same and depends heavily on genetic factors.

According to their research, liberals and conservatives have different reactions in situations for basic and original answers from people. For example, conservatives who are professional armed forces have faster reflexes when they are frightened by unexpected noises and exposed to threatening images, they react to stronger adrenaline levels and look Image faster. In addition, conservative followers have a more organized place to live, while the liberal rival is much more messy and indiscriminate.

Scientists also found anatomical difference in the brains of two human models. A study has demonstrated that the conservative faction has a larger right side almond. It is an area deep in the brain and is linked to reactions to fear and intimidation. In contrast, liberalists have more cells in the cerebral cortex (the curved structure on the surface of the mid-hemisphere) - the region responsible for recognizing repetitive errors and Adjust behavior to avoid them.

According to scientists, the choice of political bias mainly depends on the personality that has been formed at birth rather than by experience, thought and understanding. Dr. Hibbing believed that the conservative faction was born that was less subject to change but they were better leaders and more loyal employees. Meanwhile, liberals are more receptive to new experiences, adapt to change, better deal with uncertainties. In addition, they are more flexible and have a desire for life.
