I am interested in what you, the ATS community, think about the debate of nature vs. nurture.
Are our actions and personalities and everything about our lives predetermined by our genes? By how we are built, and not because of environmental
Or do we develope personality and potential through learning and environmental factors?
Personally i beleive that genes only give you the potential of something, not the certainty that it will be there. Just because you have the gene for
something doesnt mean it will be expressed. We have switch-off areas of code in the genome that can turn off individual genes. So if they are unused,
say a gene that codes for a protein used to digest milk and you dont drink any milk, our bodies will notice that this protein is unnecessary and a
waste of our resources and so is switched off. So we can have genes which we dont use.
Conversly we cant use genes that we dont have... so if you wernt born with them, you wouldnt be able to express that trait. So this means that we can
either express a trait we genetically have, repress a trait we genetically have, or we lack the trait.
This means that there is a genetic potential you are born with. There will be a maximum to everything, muscle mass, intelligence, brain size,
testosterone levels what have you... there will be a maximum (because you cant express what you dont have the genes for). However because environment
driven nature of genes, that switch off when not used, we have to expose ourselves to the stimuli that would trigger these genes... ie if you are
genetically predisposed to being big and strong (you have the right combination of genes, that allow you to grow muscle faster, better, adapt
ligaments etc.) you will still have to work to become strong, if you never excercise you may still be slightly stronger than people who do the same as
you but arnt genetically predisposed, but you wont automatically be huge.
So the question of nature over nurture and vice versa have always confused and interested me... for me its clear that you cant outperform your genes,
but how you use them depends on what you do and how you developed, making both sides wrong.
Interested in your thoughts,
