Is there any example of a non-functional (or accidentally functional) gene or protein. I mean is there any report about a DNA sequence that encode a protein (or any other molecular product) without any impact (neither negative nor positive) over the fitness of the carrier.
Any example with transposons or inteins those molecules can consider like an inner parasite, so they have a negative impact over the host's fitness (still being a fitness impact) .
If there's not any example... are we blind to this phenomenon, as a result of our own beliefs, are we molecular panadaptationism?
