4. Genetics and intelligence

Ups to today, numerous statistical studies have been done on the IQ heritability. The observed correlation in the IQ is low, except in identical twins which is 80-85% among them; nevertheless, if they had considered the relationship with their parents, they would also have obtained a low correlation.

The problem is that they have not defined correctly the composition of the variable to be studied. It seems that if they would study the correlation of the colour of the sisters' flowers or rats, as in the typical examples of Mendel's laws, they would have obtained low correlations!

It is clear that it is not a question of a simple linear relation, there exists jumps in continuous variables with random processes governed by laws intrinsic to evolutionary genetics. Establishing the relations implied by the GTCEL, it is possible to obtain high IQ correlation between the parents and their children. Therefore, it is indirectly proved the coherence of this theory of evolution.

The influence of genetics on cognitive abilities has been and continues to be an intense topic of debate because of the consequences that come from one stance or the other.

As I have previously stated, The EDI Study in my opinion shows both the hereditary nature of intelligence, strictly speaking and therefore relational intelligence in general, and a large part of the GTCEL itself.

Although statistics is a famous science due to its vulnerability to manipulation, it is also certain that this argument is often used when people do not want to recognize the facts as clear as they may be.

We will briefly look at a few points in favour and a few points against a high correlation between genetics and intelligence and at the difficulties or elements that allow for the coexistence of such different positions.

4.a) Genetic predisposition  

4.a.1 Highly gifted children  

4.a.2 Cognitive processess and genetics  

If the conceptual accuracy made on formal logic or intelligence and intuition, as variations of the cognitive processes. Indirectly, we are accepting the genetic base of intelligence.

The method of Verification of Genetic Information is performed, in this case, at the moment subsequent to the genetic transmission and even after the initial development of a new being. However, we want to conserve the adjective related to genetics in the name of this method to indicate that the genes determine the operative structure.

Due to its importance, being the theoretical base of the statistical model previously cited, it woul be a good idea to read the graphic explanation of its operativity in the case of intelligence that is included in the page of the Evolution of man of the book GTCEL (General Theory of the Conditional Evolution of Life) about the nature of intelligence and genetics with or without the application of the method of Verification of Genetic Information from a functional point of view.
