Link: High IQ genes vs. Low IQ genes

http://charltonteaching.blogspot.co.uk/2015/08/high-iq-genes-versus-low-iq-genes.html

Before the Industrial Revolution, individuals with a higher mutational load, which means a higher load of low-IQ genes (and therefore lower intelligence) had lower-than-average reproductive success due to very high (indeed, probably near total) childhood mortality rates. But since the child mortality rates fell from more than half to about one percent in most of Europe, almost all babies that are born have survived to adulthood, and most of them have reproduced. Therefore, we must assume that there have by now been several generations – in England at least eight generations – of mutation accumulation. And we must also assume that this has had a significant effect in reducing intelligence.
