I didn't "snip" anything. I typically reply to your posts in their entirety which is more than can be said for you, good sir!
I am not equating the two. I am saying that you are doing something analogous by arguing that the "optimum behaviours" in this sentence:
are equal to the "right and wrong or good and bad" in this sentence:
It is one thing to talk about "optimum behaviours" for maintaining social cohesion and for the survival of the species but it is yet another to show that maintaining social cohesion or the survival of the species is the correct moral end (i.e moral in and of itself) which you would need to show to demonstrate that this "optimum behaviour" is equivalent to "moral behaviour". I see no reason to assent to your view.
But again, what is
moral about it?
Tough! In science there is something called peer-review where someone's ideas are subject to scrutiny. If you don't like it then try something else.
Morality is usually divided into two categories: descriptive and prescriptive (this one is also sometimes called normative). There is actually a third known as meta-ethics, but I think two is enough for now.
In descriptive ethics, we simply look at the phenomenon from the outside, as it were, in a non-judgemental manner such as noticing that there are a lot of different ideas about what is good and bad and how different societies and cultures arrange their ideas about morality, perhaps whether emotions or rationality are the biggest driving forces in morality etc... and also where these ideas of right and wrong came from, whether or not divine command, culture or evolution have been important in shaping human moral sentiments etc...
In normative ethics, this is where people make claims about what is actually right or wrong. In order to do this you have to argue why it is good to do X and what stems from this. This is where you are best putting your arguments into premises in order to show the conclusions. If you do this, however, then please be prepared for people to look at the argument for signs of logical inconsistency. People will grab hold of the premises and give them a shove in order to test whether they wobble or not. Similarly, if the conclusion doesn't follow from the premises, this will be pointed out as well. And of course, the argument may be incomplete. The conclusion may be baldly asserted without being properly argued for. It might be a non sequitur. It may be incoherent.
Here are some tips if you want to demonstrate your argument in a convincing manner.
Try to make each premise easy to read. Each premise should really be reduced to a single line. Try to avoid too many clauses. Can the premise be accepted or rejected in its entirety?
Here's how I might reconstruct your argument, as I see it, although please feel free to correct me and replace it with your actual argument. Also, I will leave a blank space for where I think you have to place a premise but have refused to assent to what I think is the most logical premise so far:
1. certain behaviour is optimum for enabling
the survival of the species
2. science can tell us what that optimum behaviour is.
3. ?????
4. therefore science can tell us
what is moral.
Now, Tassman, do you agree that that is a fair representation of your argument?
If so, what is premise 3? (I have put some words in italics as a hint

)
If not, then you will post your actual argument and end this game of whack-a-mole.
