In their new book, “10,000 Year Explosion: How Civilization Accelerated Human Evolution,” authors Gregory Cochran and Henry Harpending, researchers at the University of Utah, elaborate on their previously published view that in the past, cultural persecution and natural selection combined to result in a higher percentage of intelligence genes among Ashkenazi Jews as compared to other populations. They also postulate that several genetic diseases associated with the Ashkenazi are associated with enhanced brain performance. Are you convinced of this connection?
Do you agree that there is a genetic link between intelligence and the Ashkenazi?
Yes, there is data to back up this contention.
No, cultural factors such as a focus on education and admixture with native populations must be taken into account.
Undecided, the jury is still out on genetic evidence favoring varying rates of intelligence among different populations.
