Birth of primitive art 14 : People who made first fine arts 3

This time, the change that occurred in Cro-Magnons heart is evident from the burial and the fine arts.

I examine the thing that the change brought, and also the cause.

Last time, although we looked at the influence of their settlement, it is more important that rich contacts increased into the family or the group.
Influence good for child rearing must have come out first.
When they gathered together, they probably enjoyed a long talk like present-day hunter-gatherers.
This probably grew their intelligence, language, and their culture.
Probably, this is one of the reasons in which Neanderthal who used fire and had language functions (cerebral language field and throat structure) lost battles with Cro-Magnon.

What happened to Cro-Magnons family?

A 13-year-old boy lies on the left of the figure, and an 8-year-old girl lies on the right.
They dressed with protections against the cold from head to tip of foot entirely.
Splendid spears made of ivory and the necklace of beads, etc. were added in large quantities.

This burial clarifies the difference between Neanderthal and Cro-Magnon.

Although Neanderthal also buried one person, they didn't bury small child or more than one person.
Cro-Magnon performed a burial of mother and child for the first time in the cave in Israel at 90,000 years ago.
After that, the burial examples such as two small children and three adults increased in Eurasia from 40,000 years ago.
They began to be strongly conscious of the bonds of mother and child, a family, and a group.
Probably, respecting for maternity added on prayer of fertility, and it led to Venus statue and next mother goddess worship.





Originally, because hunter-gatherers have several problems in life with a lot of people, they dispersed easily. Similarly, they are hesitant to settle down.
Something that controls this minus feeling and advances must have happened in their heart.
Although advanced technology and intelligence were indispensable to adaptation to arctic cold, unless the bonds of family or group arose strongly, the epoch would not have happen.

But, gradually woman and magician are expressed carefully, and group behavior such as the hunting that was shown a prefatory picture came to be drawn in the last stage.
Furthermore, mother and child and the women who danced were also drawn.
On the other hand, drawing carefully game animals decreased.

What happened to Cro-Magnons brain?

Neurotransmitter dopamine is widely secreted from A10 for a long time in large quantities, especially to the frontal lobe.
Although neurotransmitters are tens of kinds, a dopamine is called a pleasure substance, and have a role to maintain a feeling of happiness and romantic feeling strongly.
A10 is like the big faucet that only human beings have.

The frontal lobe takes the central role on planning, conforming to a social norm, controlling feelings, and the consciousness is in it.
When dopamine is secreted into it, people continue to have strong motivation.
In this way, the epoch happened, didn’t it?

The background in which primitive fine arts arose in Europe was the interaction of global environment and human-beings evolution, and the interaction of their intelligence and the settlement in a group.
Furthermore the brain and the gene were deeply concerned with it.

Next time, we will look at some mystery of primitive fine arts.
