Whilst the theory of evolution is now widely accepted by free-thinkers, less attention has been given to the evolution of the human brain. This work contends - and indeed proves beyond a reasonable doubt - that the brain evolved in tandem with the body. Furthermore, that brain drove the bodily evolution. It designed the human body to adapt to the conditions found on the ground. These adaptations were achieved by the brain's reaction to the input of information it received through the eyes. Just as multiple products today are designed by computer, the original computer, or brain, designed mankind for the many habitats found on Earth.
