If that is the best you can do you really are a sad piece of humanity. As usual nothing objective only abuse - there is no change in my position, just a flawed analysis and willful misrepresentation by you, matched by an inability on you part to argue in a rational fashion.
It is not instinctive and there is nothing inherited about the techniques of how one holds and uses a pencil to best effect to make a picture, that is a craft skill which is taught or learned. .It is to be distinguished from the physiological potentiality to hold a pencil which is in inherited. The flaw in you analysis is by confusing the inherited potentiality with the non inherited development of technique. .
that is the point you are evading addressing, why do we need books and/or teachers to teach us to eg read, write, make pots, carve wood, paint, etc., and that is because the ability to actually do these things is NOT inherited .
