WHAT IT IS
- Current scientific findings have revealed 52 genes that contribute to a person’s intelligence. 40 of which have been newly discovered.
- Geneticist Danielle Posthuma used a study called GWAS (Genome-Wide Association Study) which combined 13 past intelligence studies and a dataset of 78,000 individuals to look for any associations between human genomes and IQ.
WHY IT MATTERS
The recently found genes provide further support for the argument that intelligence is inherited. The new findings also give insight on how the brain functions and neuron development, as well as a deeper look into the biology behind logical problem solving.
WHERE WE ARE NOW
- While the research marks a significant step in figuring out the biological underpinnings of the brain, there are some who worry that the allure of these findings could lead to unethical genetic engineering.
- The complex nature of the brain continues to make manipulating genes to increase intelligence very difficult, as many genes perform more than one function.
