If a person embraces an intellectually wimpy evolutionistic metaphysics versus merely evolution as such as a means of explaining e.g. the diversity of life, then none of this really has an answer as there is truly no up, down, right, wrong, etc. Evolutionistic metaphysics begins with the presupposition that everything is purposeless and meaningless and so precludes the possibility of happiness as even a real thing. However, if a person manages to finally free himself from that bogus, high school caliber metaphysics and recover telos, you will stand a chance of coming to understand happiness in at least eudaimonic terms, that is to say, as the same as completion.
