Place A Human In A Water Environment And They Will Evolve To Adapt To Their Conditions.

not exactly...
being placed in water is not an environmental change to a species...it doesnt necessitate evolution...put 1 million humans in water with no air and you'll have a million dead humans..
however if the world flooded slowly and it was necessary for humans to gradually need to hold their breath longer and longer to hunt or any other basic required function to sustain life...and i think that over time, we would evolve into something like a dolphin...a mammal that can stay under water for a while...but still needs air.
