If you're smarter than the average bear, you should call your mom right now to thank her!
New research shows that children get their intelligence from their mother's side. It all comes down to genes. The researchers found that intelligence is passed through the X chromosome, and since women have two X chromosomes (men have one X and one Y), children are twice as likely to get their smarts from mama.
If you’re still not convinced, try this: The evidence goes back for decades. Starting in 1994, researchers at the Medical Research Council Social and Public Health Sciences Unit interviewed 12,686 people ranging in age from 14 to 22. Their results? After accounting for the children’s IQ, race, education, and socio-economic status, the best predictor for intelligence was, once again, the mother’s IQ.
Thanks, mom!
