Heheh, good one. :)
Wait, I can't tell if you're serious or not...

What do you expect? Do you think that in 10 years all the humans will be a new species? Evolution takes thousands of years for small changes. Humans are a relatively new species, but in about 30,000 years, it is likely that humans will be a little different then they are now. At that time, hopefully there won't be uneducated people asking why that species is still around.

Let me guess. Everything you know about evolution you learned from people who have never studied it. Right?
The process of evolution is really slow. It happens on the order of hundreds of thousands of years. Also, evolution happens when there are environmental pressures. If a species is well adapted to its environment, the environment remains stable, and no new species comes along to introduced competition, then there is no reason why the species should change.
Homo sapiens is relatively recent, probably only about 100 thousand years old. We developed such advanced tool making and planning abilities that we've mostly managed to make our environment adapt to us. This means that evolutionary pressure has dropped to nil.
Of course, if we continue to dump carbon into the atmosphere, it will probably get enough hotter that lots of people won't be able to survive, and even a small biological change that could allow us to tolerate higher temperatures might be selected for over just a few hundred years. If we don't kill ourselves off completely that is.

Because evolution is a slow process that takes tens of thousands of years. It begins in a relatively small portion of the population and spreads. It also starts small--a cat is born with slightly bigger eyes so it can see better in dark. That helps it get more prey, which makes it healthier and stronger, so it mates more and it's genes are spread through out the population. It's children have the same thing and eventually all cats have bigger eyes. Or, the cat gets eaten by a dog, and that evolutionary advance is stopped until the next time.
In the case of people: we are bigger and smarter with longer life spans than even 300 years ago. Besides, don't you watch X-Men or Heros? We could be on the verge of an evolutionary breakthrough and not even know it.

Because evolution takes a while. And we apparently have evolved - ask a doctor what the appendix is for and they'll tell you it's a vestigial organ - no longer useful to us. I imagine that eventually we'll simply be born without them.
Compared to, say, dinosaurs, we've only been around for the blink of an eye. It'll most likely be millenia before we'll change enough for it to be noticeable - unless we start doing it ourselves. Yay for genetic engineering.

Does your foot taste good?
Have you any knowledge of the ongoing changes in human development?

Not-so-intelligent-Design by believing that we are evolutionary superior we created methods to tamper with ou rown evolution, ironically

we are stable... and besides, it takes too long to see a significant change did you even read about evolution?

Nice try. Choke up on the bat a little next time.

Crocodiles have existed for millions and millions of years in a very similar form.

It takes many millions of years. Be patient.
