the answer is NO, this is because;

Some traits are accidental.  Genetics have an element of random variation whether by the recombination of genetics that comes with sexual reproduction, or by mutation, and while some changes can be selected for or selected against by the evolutionary pressure described as "survival of the fittest" there are also changes that make little if any difference to the survival of the organism or of the species, and so, they are not subject to evolutionary pressure.  Therefore they are not adaptations, they are just accidents.
