Could humans eventually grow beaks ?

A biologist at Sheffield University has suggested that human teeth may end up being replaced by a beak.

Dr Gareth Fraser believes that we may evolve such an appendage within the next few million years as it would represent an upgrade to teeth for biting and chewing. Whereas teeth have a tendency to break, rot, chip and fall out, a beak would be a lot more robust. Dr Fraser's prediction came as part of research in to why humans only grow two sets of teeth while other animals, such as sharks, grow many more.

"It could be possible for humans to evolve to grow beaks, like pufferfish, which may be more robust and practical," he said. Until that happens however, Dr Fraser is focusing his efforts on finding ways to help stimulate regular tooth regrowth to help replace missing teeth in patients.

"It might sound more like science fiction than a serious prediction, but a biologist has suggested that humans could one day evolve to grow beaks."

As does the evolutionary need for BJs.

There is a minority that thinks that historical events never happened. Even as recent as the Apollo Moon Landings.

Very positive of him to believe we'll be here in a few million years

LOL, keep it up. You are one of the funnier trolls around here.

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.

i always knew that "idiocracy" is not a comedy, but an accurate outlook into humanity's future.....

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.
