what about progression to the mean? Logically it should happen but do we see it in the real world?

I was always fascinated by the idea that human beauty is the mean. Not sure if this is actually true - it featured in an old Desmond Morris documentary. Assuming it is then beneficial IQ increases above the mean, whereas beneficial beauty is the mean.

Does it mean when a child has a higher IQ than either parent - it is down to, what Darwin would term, a beneficial variation? So a degree of biological dice-rolling randomness? Or regression to the mean still permits this swing? I'd better take some more IQ pills.

I'm busy reading Darwin's Origin of Species with one of my children. Striking to see the lengths to which he goes to avoid making any reference to the famous group of mammals, humans. It is the elephant in the room. Not sure it's environmental as maybe IQ can jump generations.

False. The reversion is *towards* the mean, not *to* the mean. Animal breeding programs would never work if the reversion was *to* the mean.

It would take many generations of genetic re enforcement, to have progression. took ashkenazi 800 yrs for 300 people to become the millions of 110 IQ average today. That also leads to many genetic diseases over enforced among them as well, like breast cancer and neuro diaeases
