Plant Sciences, Zoology & Evolution / Will we lose our nails?

Actually, I lose nails all over the place. Despite the fact that I have dozens of them, I never seem to be able to find the right one!
But, it's not that sort of nail I was thinking of. It's the ones on the end of our fingers. I don't know about you, but mine seem to be pretty much decorative. They are so flat that, if I don't keep them really short, they are inclined to fold back and cause me a lot of pain.
On the other hand, my terriers have really serious nails. They even have blood vessels in them!
So, will humans eventually evolve to have no nails at all - and will we look like ET?
