It is likely that the genes involved, which include genes that encode neuronal ion channels, have been subject to a positive selection pressure leading to an accelerated evolution of genetic changes.

As we approach the next evolution in computing as ushered in by the iPad, Microsoft and Intel are under extraordinary pressure to recover in mobile.

Furthermore, since the evolution of conscious thought in humans, there is less selective pressure to have more developed infants at birth because of the increased ability to protect human infants.
