The Human Brain; Asymmetrical & Symmetrical

The human brain carried on evolving over millions of years. One of the most important developments was that it started to become asymmetrical as it got to grips with a whole range of different functions – logic, language, the coordinated movement needed for tool-making, imagination and creative thought. The left and right hemispheres of the human brain have adapted to specialize in different skills and tasks – quite unlike the ape’s brain, which remains not only smaller but symmetrical.
