Carbon, I am afraid that is, in most circumstances, in correct. Evolution is all about the organism, not the population (with very specific exceptions).
Natural selection is a process that optimizes among tradeoffs. Almost any adaptation that has a benefit can also have a cost associated with it. Being bright red as a male cardinal may attract more opportunities with the ladies, leading to more offspring, but it may also attract more sharpshinned hawks leading to less offspring. For the trait, redness, to be adaptive, the NET effect needs to be positive. So a little increase in risk of being killed by predators can be outweighed by the advantage with the girls. But it is all about the individual, not the population.
