Cerebral Darwinism 

Cerebral darwinism is the theory that the fittest brain cells survive through the process of neurological natural selection.

After all the drugs and alcohol he did in high school and college his friends were amazed that he was still a very intelligent, articulate person but he explained that this was a result of cerebral darwinism and that the brain cells that had survived the various assaults of drugs and alcohol and various head injuries incurred in drunk and drugged out stupors, were the fittest brain cells and were actually super brain cells. Those that didn't make it were eliminated by the process of neurological natural selection.
