too intelligent to actually be intelligent?

quote[ I just suggested that with the millions of years of evolution that we have had that the best design would now be in place. ]what you seem to forget it the enviroment is not static , what was a good design can fast become a bad design when changes in temperture , rain fall, etc occur.in fact very good designs are hazardous if the creature becomes to specific to its current enviroment , and then the enviroment changes .also where there has been little change we do see very suited creatures over the long time span .. sharks are a good example ...been around ages , hard to beat in design terms fror catchuing a fish , and have had a fairly constant enviroment to live in ,and yet they lack some of the more "today" features we have . ie large brains able to build trawler to catch fish by the thousands so are we better dsigned sharks ? ?
