	You don't need any form of communication with succeeding generations.  If
so, nothing would have evolved since most organism can't do that...
especially plants!
All that Darwin said regarding "Survival of the Fittest" is that there must
be some advantage to some particular mutation.  If it's advantageous, then
more organisms with that mutation will survive to reproduce, and the others
will not.  More of those genes will be passed on to the next generation,
etc etc.  If it's a negative thing, then it will be rapidly taken out of
the gene pool.  If you have hundreds of thousands of years (and
generations) then it will be pretty well fixed in the population.  
	So, a mosquito survived to reproduce... nothing more than that is
necessary.  More to the point, the non-fit are not reproducing.
