There really aren't any selection pressures capable of motivating large changes in the human species because our environment is largely one we control and bend to our will, rather than having to coexist with in the way that any other animal has to. Even assuming that 200,000 years is some huge span of time on an evolutionary scale, our stasis wouldn't be too surprising; we're an apex species with no selection pressures to prompt us to change.Apples and oranges. Species change is dependent on major changes to the DNA through mutation. Given the prevelance of mutation in the human genome, shouldn't we have seen some major changes by now? Like eyes in the back of your head or something?
Species change is dependent on mutation AND environment. Eyes in the back of your head? OK, I will address this ridiculous response. If you noticed, there are certain patterns to the different subphylum: Vertebrata. Two legs, two arms, eyes in FRONT of the head, etc.. There are also similarities between different Phylum as the parrot beak shows us. Octopus, triceratops, even some insects. Different world, different circumstances, possibly "eyes in the back of your head" might have been so, but that is not the path evolution took here on earth.
You make people miserable and there's nothing they can do about it, just like god.

Science is like a blabbermouth who ruins a movie by telling you how it ends. There are some things we don't want to know. Important things.
