Wrap question evolution

My question began with why can some people draw and others not? What makes people have that talent? Is it the eyes or the brain? After I found that it is in the brain. the message sent from the eyes to the brain prossesses different. then I narrowed my question down to is there a way to help people to draw? Can they be taught? I found out that people can be taught to draw, but they have to follow certain tests. After I found that out my question is now, will the series of chosen tests improve the ability to draw?
