Why are some people so smart? The answer could spawn a generation of superbabies
But he is far from average. After being identified early as a science prodigy, Zhao raced through China’s special programs for gifted students and won a spot in Renmin, one of the country’s most elite high schools. Then, to the shock of his friends and family, he decided to drop out when he was 17. Now, at 21, he oversees his own research project at BGI Shenzhen—the country’s top biotech institute and home to the world’s most powerful cluster of DNA-sequencing machines—where he commands a multimillion-dollar research budget.
Zhao’s goal is to use those machines to examine the genetic underpinnings of genius like his own. He wants nothing less than to crack the code for intelligence by studying the genomes of thousands of prodigies, not just from China but around the world. He and his collaborators, a transnational group of intelligence researchers, fully expect they will succeed in identifying a genetic basis for IQ. They also expect that within a decade their research will be used to screen embryos during in vitro fertilization, boosting the IQ of unborn children by up to 20 points. In theory, that’s the difference between a kid who struggles through high school and one who sails into college.
But—and this is crucial—the implications of this math are that it will take far more than a few thousand genomes to solve the puzzle of intelligence. Given the small sample size they have so far, Hsu hopes they’ll start by finding one or two genes associated with intelligence. A recent Dutch study required more than 125,000 genomes to isolate three variants associated with educational attainment; to create a genomic predictor of IQ, Hsu says, it could take 1 million or more.
The good news for Zhao is that cheap DNA sequencing, together with more creative ways of obtaining DNA, means that a million genomes could be in reach within five years. The genomes don’t all need to be geniuses, because the IQ-affecting genetic markers they’re looking for—DNA typos that drag down intelligence—are more often carried by the 100-IQ people. That is, it’s a relative dearth of these mutations that gives people higher IQ, according to the theory.
I have always been fascinated by children who are born so intellectually gifted. Why? How do they exist? What would the world be like if everyone or most people were born with these abilities?
It must be genetic. And the method that Zhao is talking about doesn't take any Einstein to understand - its just an application of cheap gene-sequencing technologies.
I'd love to see some answers to this ancient question. And I'd love to see some capabilities emerge which would allow parents to select or de-select certain traits in their off-spring - just like the some of the disease traits mentioned in the article.
