@arcanicanis 84% of the genome deals with the brain, making it a huge target for mutation. Due to the lack of purifying selection since the industrial revolution, the gene pool has been stagnant and rotting. This has resulted in a large % of the population being unfit to survive under normal conditions. We see the prevalence of physical mutations like ugliness and morbid obesity, but we ignore than those are always comorbid with larger amounts of dysfunctional brains.
