The evolutionary solution would be to grow larger, taller and more wider in order to accomodate the larger brain mass, but since we do not use anywhere near the maximum capacity of the human brain, such a change is not necessary. The de-evolution of man wil be brought about by the lack of use of the brain mass capacity and is evident in many animalistic behavioral traits of humans in gangs, prisons, Democrat conventions etc.......
Well, no. Because absolute brain size isn't as important as the ratio of brain size to body size. A basketball player isn't necessarily smarter than a tiny Ukranian grandmother. That said, humans are getting larger, but that seems to have more to do with better nutrition, better healthcare and sexual selection and less to do with an increase in intelligence.

Speak for yourself!
I'm thinking that the required knowledge to end this dispute is apparently above and beyond our current capabilities to understand.
