I believe that when Holder is saying "Progressing" that he means "adaptating."
Well that could be a part of it, but what I meant by that was biologically growing up and then dying. Basically, you're organism function is exactly what your organism functions are, no more or less. On the biological level, the "will to live" shall we say, is basically the blind force that runs everything, and we're just that on a larger scale. In other words, progressing, we're doing it right now. We're all doing what we are "meant" to be doing, in a sense. I don't mean progression towards happiness or any goals.
Quick hit.
"Simply living and progressing," but progressing towards what? You can't have progression without a goal or some kind of ideology of a perfect being in mind, otherwise you are merely changing as an organism which isn't necessarily "progression."
This is the part where I'd normally say "progression towards finding the best possible mate," is technically how an organism progresses. Getting physically fit, getting a job, living on your own, getting a car, and being self sustaining, are all various forms of societal progression that also act towards allowing you to get the best mate possible.
I still support that biologically and emotionally that there is more to us then doing everything for getting the most/best mates we can. Part of that progression may indeed be in having children, thus implying a "mate", but that doesn't change the fact that there interactions and friendships can still be platonic because there are more factors that come into play. Logically this seems true like I've said before, and through experience this seems intuitive. The only thing that I have granted and can grant is that an attractive female has more "potential" value than one we have no attraction to. This does indeed mean that relationships that are purely platonic are most definitely tentative, or have the potential to change and focus on the physical attraction part, apply emotions and desires with it, but these are not necessarily in place because it depends on the context of the situation between you and her, and you with everyone else.
And while getting fit, getting a job, living on your own, getting a car, etc. can all be incredibly beneficial to getting a mate/a good mate, and we all may think of that prior/while doing so, but that doesn't mean that that is the driving force to doing so. In other words, things can be coincidentally instrumental to something, or be "icing on the cake".
In order to think that happiness is the intrinsic value of all actions (the ultimate goal) and still to think the theory that you support, that would mean that sexual attraction/dominance is the penultimate goal. This means that ultimately, sexual attraction/dominance is the way to happiness. Now, while this means that things you can pursuit, like my philosophy classes, is ultimately for getting the ladies, but that is not what I think of when I think of it, nor do I see it being particularly successful because I wouldn't do much with it, nor am I social with it. In other words, it wouldn't be very good, yet I love it and it makes me happy. Now, you could still say it has the potential to increase my potential with the ladies, so it makes me happy still for your reason without me acknowledging it. Let's say I grant that, but we'd still have problems because it'd still not making me very happy because of its low "sexual utility" (just realized you're advocating sexual utilitarianism XD), yet I am pursuing it as my life career and favorite passion/joy.
