Like you I didn't see any advantage of having feelings, but there is
other things in nature that have no advantage and give a better fitness. 

 It was a fun way to describe it but i think there is something good in
that teory. We know that some animal have some bad things (i mean energy
expensive for nothing) to mate with female. So somewhere in the
evolution there could be a sexual choice of ones who have emotion and
the fitness of these people rise. In that theory, feelings would be a
way to mate more efficiency.

But i think it's not true because the mating choice is certainly bound
to the resistance of the animal (to bacterie or viruses), like seems to
proove some experiment with fish, and human!

So I have another theory without experimental proof:
feelings are bad for fitness, but the way feelings exist is the same as
the way of logic and these 2 things can't be one without the other. The
gain with logic is so much greater than the loss with emotion.
I don't know if there is something right here, but i like such theories.
