Annecdata : Our primate brains has random number generators to keep our head moving and scanning the environment for threats (there a possible veritasium video on this topic). But my friend in university had a possible (gene?) modification which allowed him to focus on a particular task intently. He could ignore distractions very easily and unsurprisingly he could grok biology and physics textbooks like crazy. The fact a spider with salt sized brain can weave a web without seen examples is a proof that genes do have effects on brains and capabilities.

- CFLAddLoader 2y agoStraightforward intelligence boosting genes are valuable enough that unless they are very recent, they should already have spread everywhere. It's more likely that developing brains have a huge number of potential tradeoffs to make for what tasks they are good at and how much energy they use. Genetics and epigenetics are merely one of the tools a brain uses to decide what shape it takes, and aren't even close to the whole picture.
- graham127851 2y agoYou could say the same about genes in tons of other areas, and you'd be completely wrong. That's now how evolution works. "Beneficial" genes don't just get to spread everywhere quickly, otherwise parapatric speciation could never occur. Read the wikipedia article for Parapatric Speciation. What does "incomplete geographical barriers" remind you of? Evolutionarily our intelligence IS very recent.
