I also would personally like to know why we haven't evolved to grow a third row of teeth.Obviously we have the lifespan that outgrows the second teeth.

That is not "obvious" at all, that is only the result of modern technology and medicine, which is only a couple of decades old. Between the needs of gathering food, outrunning predators, and dying of disease, our ancesters hardly ever outlived their teeth.

Got another question of that calibre, or are you just practising your trolling skills?

Just to underline what I said before:

Our evolutionary future is not one with beaks or other miraculous encoutrements, it is a very dumb one.

Can't happen. Firstly we are a higher species than birds. That means going backwards. Most importantly technology exists to replace teeth. My dad survived throat cancer but the chemotherapy made his teeth chalk. No problem, rip out all the old teeth and replace the lot. Yes this will take money but technology will make it easier and cheaper long before this bizarre theory coin d happen. Besides, I need lips to talk, kiss etc.

What I can't figure is why in the world we would want to have beaks.  Secondly, what natural selection pressures would possibly lead in that direction.

If there are answers to these, it would nevertheless take much longer than a million years for such a thing to happen.  We were homo erectus for the most part a million years ago, not much different from now.  Evolution of things like beaks takes much longer periods of time.
