I'm seriously confused on this.<p>First, the article throws out some very reasonable sounding things, like older dads are more established and stable parents. This seems totally legit.<p>Then they start talking of a 'geek gene' that gets passed down by dads as they get older? That seems ridiculous to me. We don't even know how general intelligence works on a genetic level.<p>Overall, I feel like we put way too much stock in genetics over how children are raised. The world children live in today (screens, different types of processed food, flashy movies and cartoons) is so different than hundreds or thousands of years ago. Early childhood years are also hugely important for brain development and social skills yet we give little kids screens to keep them quiet, hooking them early.<p>Just seems like any excuse to not involve parenting is in vogue now.
