A book called the Seven Daughters of Eve by Richard Sykes is worthy of a read and talks about what we have learned about the flow of human beings populations through DNA research. Thus it is safe to say that certain members of our species have developed differently and in different ways, meaning the brain also learns differently. As Scientists look at different human brains while doing various tasks and watch which areas light up with energy as it works through these different thoughts and tasks we are finding just how unique and different each mind really is.

Yet as we learn more about the brain we indeed add more questions to our studies. Why does man need to think. Why does mankind feel the need to share these thoughts and concepts in their writings? It appears that the flow of thought may be the single most important part of life. The process of thought is probably the single most important part of human life.
