Why would "our brains" change? Because we have tv and phones?

  Nah, because now we have agrarian civilizations as opposed to tribes of hunter gatherers.

    That seems just as much of a change as phones and Internet, seen from the perspective of a brain changing... Last time I checked.. Astronauts do not struggle with farming potatoes on Mars?

  We see the world differently. IE what was a 100 IQ, 100 years ago would be sub standard today because we have new ways of thinking that allow us to do better abstraction. Plus the we've changed how we see the world. Blue is a relatively new color. It is a recent distinction between what most cultures saw as green.
