The Evolution of the Mind, The Intelligence of Humanity Is Increasing Every Decade

The Evolution of mind
As we know, humans are a species with a very high level of adaptation. Where, human intelligence is able to develop and habituate in every era development and ecosystem change for thousands of years.

Humans have always had great concern for themselves. The human ability to introspect and the desire to explore various things has changed humans into what they are today.

In 140 thousand years, the human species has turned into the most domineering creature on the planet, from being just a nomadic creature without civilization.

A civilization is a society that has reached a certain level of complexity, this complexity is characterized by the emergence and development of social aspects that include urban areas, institutionalized government, science and technology, literature and philosophy.

Nowadays, human civilization has developed rapidly and reached an extraordinary level of progress with space exploration as its culmination. This is evidence that human intelligence has developed and evolved in each generation.

In Darwin's theory of evolution, humans are creatures who undergo evolution or changes in mindset, intelligence and physical form. Although initially considered heretical, Darwin's theory of evolution was later accepted and is considered one of the most influential theories in human history.

Currently, there are many "Misconceptions" that human evolution has stopped since humans adhered to a monogamous pattern and lived life as it is now. But in fact, modern humans are still experiencing evolution even though on a small scale and slow time.

Dr Virpi Lummaa, a researcher from the University of Sheffield, said that today the human species continues to evolve just like any other species in the wild.

A group of researchers from Canada have also conducted the same study. They revealed that humans are still evolving even though the process is very slow. The researchers also provided an explanation of why today's human teeth are shorter and smaller than the teeth of ancient humans.

Some scientists and genetic researchers agree to call the current human evolution as microevolution. Hundreds of years ago the evolution of the human mind occurred rapidly, this is because at that time the development of the human brain was driven by a more modern cultural transition and also technological developments.

Although cultural transitions and technological developments encourage the development of the brain and mind, they have become obstacles in the process of human physical evolution. Where, the way of life of modern humans has a significant difference from humans who lived tens of thousands of years ago.

Human mobility which is more dominantly supported by transportation and different types and quality of food has hampered the evolution of the human physique today. However, today's average human intelligence has increased tremendously when compared to hundreds of years ago.

This is evidenced in a study that aims to determine the development of human intelligence in the last few decades through the IQ test method. In the study, scientists revealed that the tests were becoming more and more difficult, but people were still able to do well.

The research, entitled "A Cross Temporal Meta-Analysis", uses a special method through the intelligence test "Raven Progressive Matrices" (RPM) or often called Matrik's Raven.

In the test, participants will look for random patterns in various forms. This method is considered a good measure of intelligence. Overall, more than 200,000 participants from 48 countries were studied in this study over 64 years.

Since 1950, researchers have found that the average human intelligence has increased by 20 IQ points. RPM is a valid and reliable general IQ measure. In addition, there are 80 tests that are culture-free and have been widely used for nearly 80 years.

A philosopher and psychologist named James Flynn revealed that IQ tests are designed to ensure that the average result always promises a score of 100. According to him, this is a significant leap.

He also realized that the tests were getting harder, but people still got the same score, this is known as the Flynn Effect.

If modern Americans had taken IQ tests a century ago, they would have scored relatively higher, averaging 130 points. In contrast, human ancestors would have scored a very small average score of around 70 points.

This is equivalent to a 3 point increase in IQ per decade. According to recent research, outside of the United States, the biggest changes are occurring in developing countries. The IQ points of people in developing countries have increased substantially every decade.

Improving the quality of education, level of health, fulfillment of good nutrition, and the decreasing number of family members are alleged to be factors that cause the high rate of growth of IQ in developing countries.
