Adapted is the wrong word.
Specialised is the correct one.
It's easy to use the word adapted, especially when talking about evolution because adaptation is where you get your specialisations from.
However, the (a) species ability TO adapt is what rates it as a success, if you had to give evolution a 'goal', rapid/successful adaptation would be it's aim (in actual fact the logic behind what would be argued as evolution is the reverse of this, but nevermind that).
Adaptation is something we're actually slightly less good at than most, currently speaking we're the most complex form of life on the planet, perhaps the most complex in it's history.
The argument would be that a more adaptable specie, perhaps something along the lines of what we may become (if we survive long enough) with advanced genetic engineering, for example;
Being able to glow in the dark in lightless environments (interior of asteroids/barren worlds).
Being able to breath different mixtures of gases.
Being able to survive without 1/3 the nutrients we currently do.
Being able to survive without bone or muscle degradation in lower gravity environments.
Being able to survive without support devices in high gravity environments (and honestly, this really only means .5G-2G, I would find any more in either direction to be unrealistic for us, even with bioengineering).
The idea that technology and our ability to think can do the job for us is flawed, it actually shows just how badly adapted and just how badly off we are in terms of evolution.
We're specialised to take almost full advantage of the current state of things, although this is the purpose of the biology of our species it is entirely luck that we as a species arrived here and not some other specie.
We are not special and it is not our manifest destiny to survive and colonise, we will have to make that happen and a true understanding of our we effect and control our environment would be a great start towards that, eventually however the only realistic way to make it happen permanently is either advanced in the extreme (genetic engineering), or total cyberisation.
The idea that we are the pinnacle of evolution (ever) is a complete joke.
The idea that evolution has a pinnacle is also likely to be seen as a joke.
The Earth is not our cradle, and we are not rulers of it, in fact we do not get along with more than the majority of the earth and more than the majority of the earth does not get along with us (talking biosphere).
