personally, i hope something reptillian, but this is a serious question.
1. we are at the top of the food chain
2. we destroy all
3. racism is a main feature.

In order for evolution to proceed you need genetic variation that is acted upon by natural selection. Natural selection dictates that less fit individuals will reproduce less (or not at all) than more fit individuals. Without natural selection THERE IS NO EVOLUTION.
So, if you look at human beings, we have the technology to assure that all humans (or at least a random sampling) reach adult reproductive age, regardless of fitness (those 6 billion people out there must be proof of that). Hence there is no natural selection in human populations, hence there is no evolution in human populations.
Human technologies may evolve, but humans as a species have stopped undergoing biological evolution long ago. And no, it's not going on at a slow rate, and no, evolution does not happen continuously.
Unless something drastic happens you are already looking at the end product of human evolution.

Of course no one knows for sure; we can only speculate. I believe that we're essentially done. Species evolve because of environmental pressures. The human race has reached a point where we can change our environment to suit ourselves rather adapting to our envionment. As things stand, there is no incentive for us to evolve into something else.
Another reason I think we've reached our evolutionary destination involves the last item on your list: racism. We have a hard enough time incorporating members of the same species who just look different. An evolutionary change would produce a seperate human species. In order to proliferate, the a fledgling species would have to have the dominate species' (our) assistance in order to advance or even survive. We simply are not mentally wired to help one person to our own eventual detrement.
I don't accept that humans "destroy all." We've done some damage and we've done some good. We not only alter our environment to suit ourselves, but have the capacity to do this with a thought of how this will effect our decendants and other living creatures that we share the world with. We are participants, not observers. We are part of the environment and the Earth's ecosystem. Like any other species, our domination sometime results in the demise of another. This is part of how evolution works. Unlike any other creature that is ever lived, human beings have the capability to make choices that contradict our instincts.

Because we don't depend on being strong/fit to survive long enough to breed there is no method to ensure that only the fit or those with advantages survive therefore beneficial mutations are unlikely to be carried forward enough to make it into the "main" genome.
The only area we are likely to develop in are longevity and immune resistance. The fact that most people are apparently smarter today then ever before is because we stand on the shoulders of those before us.
I doubt the human race can actaully evolve further be natural methods.
Also, your reptillian comment - not likely, mammals evolved from the pre-cursor to reptiles, it's not likely to reverse under these conditions.

There is no preset evolution path. Evolution depends on environmental factors and adaptations to those factors. Look at the environment and see what there is to adapt to and start to think about what sort of adaptations would be beneficial.
Also, evolution is not an overnight thing. It is like a glacier, it is moving but you cannot see it moving. It could take thousands of years for an adaptation to be noticed.

The humans of tomorrow are descended from the people of today who have children.
So: who is having children today?
Women with educations and careers have fewer children than those who don't.
So, in the future, expect women to be less interested in having careers.

seen as though global warming is happening at a faster rate we will probably end up being reptiles for those in hot areas lol and for those who will be flooded fish. wow right back to the start! like a circle
