With the emergence of human culture and the cultural ability of modern humans, something new and unprecedented is emerging.

Why does culture develop? The mind? What are the reasons? What is the cause for this innovation that will fundamentally change the world of the human species? How did the brain become the basis of the human mind through a functional change?

The second question: What is new? How can we specifically describe the new issues that arise? In his review of Tomasello’s book The Origins of Human Communication, Jürgen Habermas writes:

After the increases in size of the human brain had stopped, cultural learning processes replaced genetic adaptation. What other animal species lack is the transfer of symbolically stored knowledge from generation to generation, such that it can be revised and expanded in the light of new experiences.
(Jürgen Habermas 2009; Es beginnt mit dem Zeigefinger, in: DIE ZEIT No. 51/2009 of 10 December 2009, p. 45)

Hypothesis 8

The biological causes

The first task is to describe the biological mechanisms that led to the development of the human brain. The biological causes for the development of the human brain, brain growth and the end of thereof must be explained before the beginning of the cultural achievements of Homo sapiens are explored.

The second task is to describe how the existing human brain, through a functional change, could become the biological basis of the mind.

Explanation:

If I can’t make out the details of an object well enough, I would make use of a magnifying glass. If I still want to be able to see finer details or material structures, then I’ll use a microscope. If I want to research a subject scientifically, one possible method is to divide the subject into many small problem areas, each of which can then be examined individually. In the end, the results are combined once again.

If the brain is the biological seat of the mind, the two are therefore not identical to each other.

Moreover, the mind has its own identity, which must be explored and described. The basic form of the mind or culture arose in a special historical situation. With the mind a new level of existence was born,

emergent characteristics of individuals and social groups arose; characteristics that can no longer be adequately described with the biological theory framework but which require the use of humanities or social science theories.

In The Cultural Origins of Human Cognition, Michael Tomasello drew attention to what, on an evolutionary scale, was a short period of up to 250,000 years, during which man’s cultural development has taken place up to this day.

We know from embryonic development, and Darwin has stressed in great detail that

conclusions about phylogenesis can be drawn from the ontogenesis of individuals of today. Why shouldn’t this line of reasoning be applied to brain and mind?

Every infant already has a human brain before it can absorb cultural stimulation from its environment. This should also apply for phylogeny, the tribal history of humans. The chronological sequence of brain and mind development is basic but raises new questions about the development of the brain.

From the moment the human brain exists in its present form, there is the possibility of the emergence of the human mind and human culture – but only the possibility.

II.      The solution

Hypothesis 7

The succession of brain and mind

As the basis of the human mind, the human brain is an evolutionary innovation that couldn’t have developed gradually but rather only through a change of function. The co-evolution of mind and brain is replaced by another model of thinking, that of the temporal succession:

First the human brain developed, then the human mind developed. First the human brain had to be created for biological reasons. Only then could the human brain become the basis of the human mind through a change in function.

Explanation:

The biological basis of the human mind is the human brain. Therefore, the development of the human brain is a central question in the development of human culture and the human mind.
