No, human evolution, the variations in the human species, has not stopped. Instead it has changed parameters that cause different human beings to reproduce more than others.
Some might point to birth control and education and say that people are actually as a whole devolving as poor and primitive people of limited education have larger families and government systems have been set up to support what "natural" selection would mitigate against.

It is pretty interesting how we supposedly jumped from some primitive ancestor with the brain capacity of a chimp to modern humans in a very short "evolutionary" timescale and have remained basically static ever since. But I guess if you buy the punctuated equilibrium theory where neutral genetic mutations build up over time until "blam" you get something new, you can believe just about anything "could" happen. I always wonder why we don't see reptiles in the process of changing to birds anymore, or fish to mammals. It seems like if evolution were this slow process over time, these changes that supposedly so readily happened in the past should certainly be happening the same way now. The earth should be teaming with species in the process of changing into other species. Maybe I'm just trying to be logical where logic need not apply though.

No.
A significant minority of Europeans have a resistance to the AIDS virus which is not found (or possibly found, but in statistically insignificant numbers) in other racial strains.
I suppose you would consider the ability to fight off HIV a positive adaptation.

As long as environmental change continues, evolution will continue. The problem is that humans are changing their environment faster than they can adapt to it. Evolution is a slow process - change, these days, is very fast.

No, actually. Because of the increasing diversity in human life, human evolution has actually sped up some, not slowed down.

I think its the calm before the evolutionary storm. With new advances in growing organs, stem cells, nanotechnology, and of course computers, by the end of this century I think we will be directing our own evolution in many weird and wonderful ways.

No, there are still illnesses that we are unable to fight off. That is why you should let your immune system fight off small illnesses like, a cold or the flu. By making it stronger, you are helping your body to adapt and fight off these kinds of illnesses. If we adapted so far that our bodies could successfully tackle things like TB without medication, that would be huge.

To an extent yes. But social natural selection still effects our evolution.

no we are still evolving and adapting

Just a few examples to get you started, there's a whole lot more going on out there in the gene pool.
