On the one hand, some people feel that comprehension is genetically inherited from parents. Every process and formation depends on tiny pieces of biological information that are received from parents and result in unique traits.The recent evidence from researchers depict that brain development relies on mothers, because this vital gene for this process is inherited from them.Finally, it is often said that brain-damaging diseases are mostly gene based.For instance, people with predisposition to imbecility have more chances that their offspring will be sick with dementia.
One the other hand, thought, one major factor that affect brain power is environment where individual was born and raised.For instance, the greatest scientist of the 20th century were raised that education is the most important thing and were taught various subjects from childhood.Furthermore, recent study was done to understand the factors for scientific success of Albert Einstein and other innovators and it suggest that place of education affected them the most.For instance, Nicola Tesla awakened his interest of electricity after being in lecture of the professor in of the greatest study institutes of the time,where he also gained friend with similar interest to physics. Lastly, knowledge of individuals is limitless and it is shifted by experience obtained in either theoretical or practical ways. It is important to read books to develop critical thinking and open-mindness.
To sum up, my own feeling is that the template for brilliance is created by genes and later it is filled with wisdom over life and can be passed only by words.
