Last Stages
While I agree with Frog's statements, there are some mitigating factors at work in modern human populations that reduce the effectiveness of normal natural selection.
The rate of change in the modern world outpaces the rate of mutation.
Yes, the rate of change in the West is much faster than it is in, say, sub-saharan Africa, but overall, the amount life everywhere has changed in the last 500 years is far greater than the amount of change that took place in the 5000 years before that.
Additionally, humanity is insane. Being slightly better able to survive drought might be selected for, but a better adaptation would be immunity to ethnic cleansing.
However, the light has not gone out on human evolution -
Here are some things to look for in the future:
Immunity to mercury poisoning
Immunity to solar radiation
You feel me?

Why can't they be joined
can someone tell me the reasons why creation and evolution cannot be joined?
Here's some perspectives.
1) They can be, without a problem, if your spirituality / theory of creation is "God set up all the rules and set the ball in motion." Hardly any supporter of ToE would argue with this, as it has little to no effect on the processes of evolution itself. This is the Catholic Churches stance.
2) They can't be - The Evolutionist side. Biology is a science, as such it adheres to certain rules true of all science. Namely that the world in which we live in behaves the same now as it did in the past, and that what we observe is real. If these principles are false, all bets are off. Evolutionists can't accept Creationists view because they hold that the observable world behaved very differently in the past (ie different rate of radio active decay.)
3) They can't be - The Creationist Side. The Bible is the word of God, it is not up to interpetation by man. Evolution contradicts the Bible, and therefore is flawed in it's premise.
I'm sure there are many subviews and nuanced inturpretations, I'm just trying to give a primer of block concepts.

Where are we headed
Back on topic: Where are we headed.
This is all rank speculation, of course. But here's some guesses I would make --
I saw recently that there was a genetic link to AIDS susectablity and resistance. (This has NOTHING to do with methodology of exposure). It seems that certain people when exposed are much more likely to become infected than the other group facing similiar levels of exposure. I think this was discovered in a study of prostitutes in Africa, but I may be combining two different articles in my head.
Anyway, if we do not find a cure or vaccine for AIDS and it continues to spread as it has been, it will be a major influence on our evolution.
I would also suggest that resistance to various birth control methods is being selected for, weither it's the pill, or spermacide, or whatever.
If the ozone layer contunies to deteriorate, expect darker pigmintation to have the upper hand. As well as ability to resist drought and famine.
None of these would be physiologically apparent, but I believe in them nonetheless
