A team of researchers with members from Iceland, the U.K. and the Netherlands has found a genetic factor that plays a role in how much education a person might attain over their lifetime and that the factor is becoming less common. In their paper published in Proceedings of the National Academy of Sciences, the team describes how they analyzed genomic information in a national database in Iceland and what it showed.

Prior efforts have demonstrated that the more education a person has, the fewer offspring they are likely to produce. This has caused some concern among social scientists, as it suggests that we as a species might be evolving to become less intelligent beings. In this new effort, the researchers sought to determine if there might be a way to see this process at work.
