I found this fascinating article In the Human Brain, Size Really Isn’t Everything – NYTimes.com in the NY times describing research by a couple of brain researchers with a theory to explain why human brains are different from mammalian brains. It is not proven but it is fascinating to think about the reasons why we humans are that bit special.
I also find their explanation fascinating in terms of our digital world of silicon chips because I see the same theory unravelling there and time will tell if the same pressures to processs information that lead to our brain structure lead in some way to similar designs in computing. Just theory for now but fascinating.
