Scientists believe they have found evidence that points to not just one but two networks of genes that could influence intelligence, according to the Guardian.
The Imperial College London's Michael Johnson and his research peers have published a report in Nature Neuroscience and said they also believe that these two genes might be controlled by another "master regulatory system."
The question of intelligence has always been a debatable subject, with various factors that can contribute to the nature of intelligence.
"Intelligence is a composite measure of different cognitive abilities and how they are distributed in a population. It doesn't measure any one thing. But it is measurable," said Johnson. "We know that genetics plays a major role in intelligence but until now haven't known which genes are relevant. This research highlights some of the genes involved in human intelligence and how they interact with each other."
Currently, it is believed that about 40 percent of intelligence is genetic. More research could lead to breakthroughs in artificially enhancing it.
"The idea of ultimately using drugs to affect cognitive performance is not in any way new. We all drink coffee to improve our cognitive performance," added Johnson. "It's about understanding the pathways that are related to cognitive ability both in health and disease, especially disease so one day we could help people with learning disabilities fulfill their potential. That is very important."
