While your idea is interesting, remember that evolution involves two major processes: the randomness of genetic mutations, combined with the effectively non-random component of natural selection. A random process can optimize the "genetic switches" when passed through the filter of natural selection, simply because "wrong" changes to genetic switches lead to death and no offspring, while "right" changes to genetic switches lead to survival and passing on of genes. Over thousands of generations, probability dictates that "right" mutations add up over time, causing species to diverge and evolution to occur. The genetic switches affecting increased cognition in our ancestors were beneficial for survival and led to gradual divergence from a less-intelligent common species.

Thought provoking, thanks for sharing.
