Project deCODE, a company involved in the analysis of genomes from Reykjavik, reports that a group of genes that predispose people to conduct more time on education, began to appear a little less frequently in the DNA of Icelanders for many years 1910-75.
Intelligence. If provides success in life?
the researchers used genetic information from more than 100 thousand. people to see how hundreds of genetic variations that affect their achievement in education. And whether these patterns are genetic somehow change. Found a small refraction in the number of “genes and education”, involving the reduction of the natural desire to give people your own skills.
it is important that the genes That are involved in education also affect fertility. Consequently, the persons named in the DNA of more genes, education has tended to… to have fewer children than others. This is offended of scientists to the formulation of the thesis that these genes are becoming less common because better wyedukowani people are investing less of their genes of intelligence in areas of the Icelandic gene pool
If you pull this topic further, it can be concluded that educated people are slowly dying out on their own.
But scientists argue that in the last hundred years of human iq grew at a rate of three points for the decade
As can be seen from the studies, spend more time on education and to make a career is not the only reason why higher educated people have fewer children. Many people with more genes, education than the average before plunging the education system, and decided on a smaller number of offspring.
I’m talking about the fact that education or career opportunities, which carry with them to school, prevent us from having more children, explains Dr. Kari Stefansson, who led the study. – If we are genetically predisposed to long-term education, we also are predisposed to having fewer children, he added.
However, that it was tempting, mylilibyśmy, however, saying that every generation of humanity dulled. It’s a bit more complex.
This, in turn, the researchers argue that we are getting taller, but not smarter.
first, the effect of the “fade gene” is small. The work is published in written form, “Proceedings of the National Academy of Sciences” suggests that corresponds to a drop by about 0.04 points of IQ per decade. On the other hand, Dr. Stefansson believes that if this trend utrzymałaby through the centuries, its impact will be clearly visible.
- Small effect, but stacked for a long time, which means that it will have a dramatic effect on the genetic predisposition to the achievements in education and until something is deleting genes in our DNA will not stop, we ever have a society less educated, he explains.
Other researchers have noted, however, genes have only a minor effect on our education. There are many studies that try to prove that people are becoming dumber, but the consequences of these efforts of scientists, in my opinion, argues Melinda mills, Professor of sociology at the University of Oxford.
- Our education, what and how many children we have, largely, behind him, in which we live. And this environment certainly surpasses the influence of genetics. It ‘głupienia societies’. For many years, which was estimated from icelandic researchers, more people received vocational education, while women can learn now from 3 to 4 years, longer than in 1910!
Jonathan Beauchamp, an economist from Harvard University, published last year work, which proves that natural selection does occur, but very carefully and slowly. However, forecasting future trends is wróżeniem of coffee grounds, because no one knows what changes in culture and society will bring the time.
Dr. Stefansson agree that changes in the environment, including changes in the education system and its accessibility, can outperform any influence genetic. It is reported that the average IQ of Icelanders increased by almost 14 p. between 1932 and 1978, what was the result of socio-economic and technological changes that raised the education on a mass scale. – There are many different things in the environment that can stop the deletion of genes of the formation with DNA. The issue is that they do occur, said Dr Stefansson.
what do you think? [TEST]
Ewan Birney, Director of the European Bioinformatics Institute in Cambridge, is afraid of another is a wrong interpretation of the results. Someone may inadvertently be understood that the desire to learn is determined by our genes, so those who had problems in school, first, shall be exempted from liability for their own unwillingness to learn. Second, it suggests that no changes in education systems are meaningless, because there are people who “never learn”. Such reasoning is not true! What these people don’t climb on the ladder of education can also make a difference, alas, from the evil system of education.
Go, so I think. How and where to go to make the brain work better?
