Are there any examples of organisms that completely contradict the theory of natural selection?

Evolution by natural selection (including artificial selection, humans are also part of the natural world) requires 4 things:

* Offspring are similar to their parent(s)
* Imperfect copying system (in terms of reproduction)
* Variation amongst individuals of a species
* Limited resources

Find a species that species that isn't of this nature and you'll get yourself an organism that doesn't evolve by natural selection.
