"Tied to" is pretty loose.  Most individuals goals are "tied to" evolution (I 
wouldn't say that evolution has goals except in a metaphorical sense), but it 
may be a long and tangled thread.  I like to eat sweets because sugar is a high 
energy food and so a taste for sugar was favored by natural selection.  

But my fitness and the fitness of the human species are not the same thing.  I 
have type II diabetes and so a taste for sugar is bad for me and my survival.  
But natural selection cares nothing for that; I've already sired as many 
children as I ever will.  

The individual goal of living forever is at odds with evolutionary fitness - if 
you're not going to have any more children you're just a waste of resources as 
far as natural selection is concerned.
