evolving towards dumbness

Sewall Wright, an American geneticist known for his influential work on evolutionary theory, proposed the idea of fitness landscapes. The fitness describes a certain genotype or phenotype performance in the environment. As a species evolves, its fitness changes. As the environment changes, the specie's fitness also changes. When you reach a peak in the fitness landscapes, there is no way to achieve higher peak, but go through a valley. In the last century we clearly reached a peak in the development of human intelligence. Now we experience a dumbing down process. Dumbness is spread everywhere. Dumbness procreates faster then intelligence. As result of this evolving process, the world is going dumb. We are going down the hill.
