hmmm... *sees that this thread has been off-topic for quite some time*
Anyway, I thought I could post this picture from my last year's biology book in here... It's a picture of what we humans could look like in the future. Pretty, eyeh?

1. The eyes will become smaller and pig-like, so they could tolerate the air pollution better. A protecting membrane will develop over the eye.
2. Because of the increasing noise, closeable covers will develop on the ears.
3. While there's "smog", people will have to be connected to breathing devices. For that purpose a hole will develop to the rib.
4. Because of the lack of drinking water, kidneys will produse solid urine, which will save water.
5. Foot will become weaker, because they're used less and less.
6. The greenhouse effect will grow stronger and the climate will get warmer, so hair becomes unnecessary.
7. The nose will become bigger, so it could clean the incoming air better. Thick nose hair tufts will filter soot and pollution drops.
8. The lungs will expand, so they could take the few oxygen, that is left, from the air.
9.Liver deals with the poisons in our body. Because of all the poisons, which will end up in the body, it'll become larger.
10. Skin has to be thick and has to have many layers, so it could deal with all the poisonous chemicals in the air and water.
This isn't supposed to be serious. At least, not entirely...
There isn't enough time for these kind of changes to happen. If the future was like described in the texts, it would destroy the earth and the human kind so fast, that there wouldn't be enough time for that kind of changes in our looks.
As an answer to the original question, yes, we are evolving the whole time. It is called Cultural Evolution. But I think Biological Evolution isn't happening any more. Well, it can be, but it's so slow...
