Geode, <So you're saying that environment is as or may be even MORE important than DNA. So why the heck are you going on and on about gender?>
I didn't say environment is as or may be MORE important than DNA. Where the heck did you get that idea? No DNA = no brain, no matter how much environment you provide. Sow's ear = sow's ear, no matter how much environment you provide. Female brain = female brain, no matter how much environment you provide.
You asked:
<<How much of what happens in an individual's brain development is a result of environment: encouragement, discouragement, nutrition, exercise, education, etc. vs being a strict function of DNA? > >
I replied:
<All of it of course. 100%! No nutrition = the fertilized egg dies. >
You need the DNA plan. Then, you need the construction materials and learning to build the plan.
That doesn't mean you can take any DNA plan and turn it into a maths genius at Harvard. It doesn't mean you can take a female foetus and turn it into the world champion mathematician as reliably as a male foetus, even if they were identical zygotes with the same basic plan, which become male and female during development, as happens at about 3 months gestation.
I'm going on and on about it so you can finally understand what the heck I'm saying.
