During the process of selection, individuals having disadvantageous traits are weeded out. If the selection pressure isn't strong enough then mildly disadvantageous traits will continue to persist in the population.
So the reasons for why a trait is not evolved even though it may be advantageous to the organism, are:
There is no strong pressure against the individuals not having that trait. In other words lack of the trait is not strongly disadvantageous.
The trait might have a tradeoff which essentially makes no change to the overall fitness.
