5. Evolutionary genetics and neuroscience

5.a) Brain memory inheritance

Section VI of the General Theory of the Conditional Evolution of Life proposes the EDI Study - Evolution and Design of the Intelligence to validate the theory and essential aspects of evolutionary genetics and neuroscience of the intelligence.

The statistical research on the evolutionary genetics of the intelligence and cognitive neuroscience achieved great results and it is available online in the book the EDI Study.

While in the analysis of the intelligence it is possible to speak about a general intelligence; in memory studies is not feasible due to its variety.

A type of statistical research might deal with the evolution of mathematical memory; the memory that it demands certainty in the answers, and which should behave like the evolution of intelligence.

At the same time, it would not be surprising that other types of memory, like normal memory, or the memory capacity related to the language, that have the characteristic of admitting errors, were consequence of the same genetic information, but under the assumption of not external verification.

In other words, for the linguistic memory our brain with the information of both ancestors develops a mechanism without requiring the confirmation between both. Something similar could happen with the intuition that sometimes is very powerful but one cannot be certain about it.

The verification of inheritability of memory requires a much more complicated model of evolutionary genetics than that of intelligence and it will be necessary to have measures of partial capacities for the different potentials of the memory stratum or from the special memories.

Neuroscience should provide models of the brain’s functioning to allow studies about memory in depth, but despite the advances produced, it seems that a solid model still does not exist.

The figure shows us the effect on the cognitive capacities of possible descendants within the opposite assumption to the VGI method. The expression of the capacities will follow an additive mathematical law instead of the law of intersection that we have studied in the evolutionary genetics of the intelligence.

The figure design implies a simplification of the model of evolutionary genetics and neuroscience; it supposes that the addition is equal to the potential of the major gene, thinking that the whole potential of the minor is included in the major one.

This is the case of the evolutionary genetics of normal memory. Something similar to the relation between evolution of mathematical and normal memory can occur with the evolution of the intuition, which sometimes is very powerful but one cannot rely on it, with regard to the evolution of the intelligence.

In any case, an evolutionary genetics and cognitive neuroscience model for medium and long term normal memory needs to take into account the following aspects:

  • Reliability of normal memory

    The effective potential of normal memory will depend on a similar mechanism to the intuition that would imply the opposite hypothesis of the functionality of the method of verification of the genetic information VIG.

    In other words, the mentioned potential in neuroscience will follow the rule opposite to the general intelligence described in the book about Intelligence, Intuition, Language and Creativity of the Cognitive Global Theory.

    The basic reasoning in the evolutionary genetics context is that a mistake from the normal memory is not very serious and therefore it does not require the levels of reliability that guarantees the cited VIG method.

  • The effect of simple complementariness between intelligence and memory

    If we think about the functional complementarity of the intelligence and memory in neuroscience, it might assume that each additional unit, for example, of intelligence will increase the total potential not in a unit, but in the quantity of the total memory. In these cases, the complementarity might follow a mathematical law of more or less attenuated multiplication.

    The section about Complementary Characters and the Origin of the Species in title IV of the online book of the General Theory of the Conditional Evolution of Life comments this effect of complementariness from a more general point of view of evolutionary genetics.

  • The effect of complex complementariness between intelligence and memory

    Memory depends on its genetic structure and on the power of manager of the said structure or intelligence; therefore, its efficiency will result from the effects of complementarity to occur.

    The effect of complex complementariness takes place due to the involvement of the intelligence in the processes of global information system of the memory; it is to say, the intelligence as a memory manager, and not of his logical typical processes.

    In neuroscience, the intelligent reasoning capacity of the brain will depend on the logical processor and the available information (simple complementarity effect); but at the same time, the available information depends on the above-mentioned processor, when it worked for the classification and storage of the information in the memory (complex complementarity effect)

5.b) Language, linguistic memory and linguistic reasoning

In the specific case of the research in evolutionary genetics and neuroscience of linguistic memory, the brain might act choosing a word, for example, depending on the first proposals that it would receive from the storage system of linguistic memory.

It is opportune to emphasize that, in this occasion, it is a matter neither of the employment of the method of verification of the genetic information VIG, proposed for the evolution of the intelligence, nor of his opposite but of a different one. Let us remember that in the VIG method it expected to receive all the proposals of the involved mechanism and needed a great uniformity (verification) to the acceptance whereas, in the opposite case, only needed a certain majority. Now the acceptance takes place on the first proposals with a minimum repetition.

Let's say, to clarify with numerical information the previous paragraph, that there would be validated the first five words which are repeated 50 times; in this way, it is not necessary to wait for the completion of work of thousands of million neurons that might be involved in the process.

Carrying on with this argument, and remembering that the manager of the memory is similar enough to the intelligence; It would be the linguistic memory manager the one that would act proposing the first words that its internal mechanism provides it.

The global language process would have as primary elements, on the one hand, the linguistic memory, that conceptually contains the stated manager of this type of memory and, on the other hand, the language manager in strict sense, who is the oral expression manager of thoughts and feelings.

In other words, the language manager as well as the linguistic memory manager applies neither the method of verification of the genetic information VIG, proposed for the evolution of the intelligence, nor opposite, but a different one, which would act in an intuitive form but much faster than the intuition.

The complementarity power of two characters that, as in this case, do not demand the method of verification of the genetic information VIG, it should be far superior to that of the individual characters when they apply the VIG. This could be the reason that the capacity of human language and its evolutionary genetics are surprising from the perspective of the neuroscience.

The inheritance and evolution of this combined power might be a subject of study through statistical analysis because there are methods to measure the variables involved.

A philosophical trend supports a strong constituent of genetics in language. The linguist Noam Chomsky is the most important representative of the above-mentioned trend, called innatism in contraposition to the constructivism trend. Chomsky affirmed, many years ago, to have identified common elements to all the languages of the human beings, what it meant a genetic predisposition to the language development.

The genetic nature of the language has met reinforced by the recent development of a particular gene that it significantly affects to the construction of phrases of language without affecting other personal capacities, or what we might denominate general intelligence, of the individuals in the genealogy of an entire family subject of study.
