This stuff is mentioned in the book Behave: The Biology of Humans at our Best and Worst by Robert M. Sapolsky. I'd recommend reading it. Not advertising it either, I'm aware Reddit has advertisers for stuff.
I'll link the book in case you may want to give it a look at, what he covers is great, along with environmental disadvantages/advantages to brain development:

Robert Sapolsky's relatively recent book, "Behave".
It is phenomenal.
I used this YouTube Channel in the past when I was taking Biochem. He has some good videos on genetics and biochemistry.
Robert Sapolsky is a professor of biology, and professor of neurology and neurological sciences and, by courtesy, neurosurgery, at Stanford University. You can find his entire intro course here:
I would highly recommend his most recent book as well:
The book you need to read to understand what happened here is Behave
In a nutshell, people believe what they want to believe... Elizabeth surrounded herself by powerful, old men who knew nothing of science... She impressed them, made then feel like a million dollars and promised them money and power... They wanted this to happen so they believe her even when others saw through Elizabeth and warn them
In their minds (EH and SB) they believed they were smarter than anyone around them and that all that was needed to produce the next revolutionary tech was to whip it out of people... The concept that very smart people had tried to accomplish this for decades was completely alien to them
> Heritability scores are relevant only to the environments in which the traits have been studied. The more environments you study a trait in, the lower the heritability is likely to be.
He goes on for several pages, describing the ways the surrounding environment can change an organism's gene expression, and I think this quote best summarizes his point:
> Here’s a rule of thumb for recognizing gene/environment interactions, translated into English: You are studying the behavioral effects of a gene in two environments. Someone asks, “What are the effects of the gene on some behavior?” You answer, “It depends on the environment.” Then they ask, “What are the effects of environment on this behavior?” And you answer, “It depends on the version of the gene.” “It depends” = a gene/environment interaction.
