There is a lot of work going on in the field of epigenetics. Changes to the epigenome do not affect our DNA, which is relatively static, however most memes are transferred by word of mouth and the various other ways in which human beings communicate.

They develop in the individual brain structure in the same way as other learnings, during a single life span.   

During our lifetime, our brains develop an incredible complexity. This complexity is not  genetic in basis. Our 19,599 protein-coding genes are simply not capable of determining the structure of the brain. Put it this way, the human brain has roughly 100- 200 billion neurons, comparable to the number of stars in the Milky Way. During our lifetime,  each of these develop several thousand connections to other neurons.

This comes up to a total of 500-1000 trillion connections within the brain. No computer on earth has that many connections, and if you divide 500 trillion by 19,599, it's pretty obvious that brain development doesn't have a basis in genetics.

So............................................

.......as individuals, each one of us is [almost] infinitely more complex, than what we may, apparently, seem to be.




Knew that.

Job 7:17
What is man, that thou shouldest magnify him? and that thou shouldest set thine heart upon him?
18  And that thou shouldest visit him every morning, and try him every moment?


Psalms 8:3
When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained;
4  What is man, that thou art mindful of him? and the son of man, that thou visitest him?
5  For thou hast made him a little lower than the angels, and hast crowned him with glory and honour.




.....and more, but i won't bore you, coz muso detests me posting related scripture.

I'll get Spot to translate for you.

And yet, the vast majority of brain development is universal.  Everyone uses it for regulating the internal environment, language, motor skills, basic cognition - what else does this suggest but a strong genetic component? 
Just remember the golden rule - nature AND nurture, not nature VS nurture. Why must we keep pretending the brain is an exception?

No, that was speciific to that topic.

That's right, but they are acquired by all humans, regardless of the massive variations in environment. 
How can that be, if there is no genetic basis?

Genes are memes in this :

Both reflect the will of the first cause : To Transfer Symmetry.
