Conversely, I think you underestimate it.  You cannot talk about human 
psychology without talking about the evolutionary process that created 
it (well, you can, but you can also be wrong).  The human mind is a 
huge mystery until you look at it from an evolutionary perspective, but 
evolution lets you tear it apart and understand why the human mind 
works the way it does.  We don't understand everything and sometimes 
theories are revised (this is science, after all), but the important 
insight remains that humans and their brains are products of an 
evolutionary process and are shaped by that process.

Of course not, but this misses the point.  When we talk about moral 
behavior in humans, we talk about behavior that the human believes is 
good or bad.  It makes no difference whether there is external morality 
or not; the human decides based on an internal sense of morality, which 
is, incidentally, a product of human evolution.  It should be 
unsurprising that behaviors humans believe to be good benefitted the 
reproduction of genes carrying the genotype leading to such beliefs and 
that behaviors humans believe to be bad hurt reproduction of genes 
carrying the genotype leading to such beliefs, because good and bad 
are, inside the human mind, just another way of talking about desirable 
and undesirable.  The confusion comes when trying to prescribe external 
morality to humans or prescribe one human's morality onto another human 
(thus we get the idea of an evil scientist).

Human brains are information processing mechanisms, so why do you 
suppose that memes and feedback are evidence against evolutionary 
psychology?  Memes and feedback are both products of evolution of the 
human brain, so just because there may not currently be any 
explanations of these topics in evolutionary psychology (and I doubt 
either of us are well enough read in the literature to be sure of 
that), that does not mean they are evidence against evolutionary 
psychology.  For something to be evidence against evolutionary 
psychology, it must either be evidence against evolution or evidence 
against evolution being the process that created the human brain (like 
proof that aliens visited earth and arbitrarily changed all of humanity 
by design).  A lack of current explanation of how a particular 
psychological phenotype evolved does not a case against evolutionary 
psychology make; only a further research question does it create.
