Lots of people seem to think that we're not evolving any more and that's even among people who believe in evolution in the first place. In fact we are evolving all the time we just don't notice it. People today don't look the same as people from 300 years ago in lots of subtle ways. People are taller and have healthier teeth for a start.

But what's next seems to be the big question of the day. When this question rears it's head you normally hear people wishing for things like tails and wings and so on. But I think we'll all agree that this might be a bit much. I reckon the next thing we need is... Ear flaps.

They would work in the same way as eye lids so that when a loud noise came about then your ear flaps would close to protect you from it. They would have to let some noise though otherwise it could be dangerous but it would be really good.

The best thing would be if they were controllable. At the moment when you're stressed there is nothing nicer than just closing your eyes for a couple of moments and shutting the world out, imagine how much nicer it would be if you were able to shut the noise out a little bit too. I think there would be a natural advantage to people who could close their ear flaps to sleep, but once they were under their flaps opened up again. That way they could hear fire alarms and so on. The alternative would be, it's fair to say, a bit rubbish.
