Human Intelligence Explained through Number of Genes in New Study

What impacts the level of human intelligence has always been a debatable topic for decades now. A new study conducted by almost 80,000 people and published by Nature Genetics, managed to identify the number of genes that are likely to be involved in influencing the level of intelligence level of a person. Intelligence’s dictionary definition is the capability to understand, learn, or deal with situations logically. Humans as well as animals display various forms of intelligence, generally critical for endurance. Human intelligence initially started as being “reactive” and then reached out to be “proactive”. After the initial challenge of survival was addressed, humans turned to employ their intelligence towards the development higher skills related to technology and arts.

Briefing the Experiment

The new study employed known as “g-factor” for measuring intelligence. The g-factor is considered one of the most unbiased methods used for scientific research at present. The researchers examined the scores of 78,000 people of Europe in order to look for genes and associated genetic factors that hypothetically influence the human intelligence. The genome-wide association study or the (GWAS) was carried out to assess links between SNPs and a particular trait. This specific enabled the scientists to identify almost 336 noteworthy SNPs.

What was the ultimate outcome of the study?

The scientists involved in the project revealed that the strongest genes were actually linked to intelligence and are also involved in the pathways that play a crucial part in the administration of the development of the nervous system. The most important SNP was discovered inside FOXO3, a form of gene that is involved in the process of insulin signaling and the strongest gene was CSE1L, the gene involved in cell proliferation and apoptosis.

Henceforth, this paper initially suggests that human intelligence relies on the molecular mechanisms that aid in the preservation and development of the human nervous system and intelligence can be explained through genetics.
