What if g isn’t real and there actually isn’t any general intelligence, it just looks that way because of the diversity of selection pressures on areas of the brain?
g is the ability to process complex information. It’s certainly possible that if selection pressures caused improvements in the “math” part of brains but because of tradeoffs caused a decrease in the “hand/eye coordination” part of the brain then g as measured by intelligence tests would go up.
Sorry, this doesn’t make sense to me. My objection is that the information processing doesn’t have to be portable. If it’s not portable, then it’s not general. If it’s not general, there’s no g.

Why is this inconsistent with g?
Because in that case there is no general intelligence for g to measure.

That’s all.
