I feel you are taking some concepts that you think aren’t very well defined, and throwing them away, replacing them with nothing.
I admit that the intuitive notions of “morality” are not fully rigorous, but they are still far from total gibberish. Some smart philosopher may come along and find a good formal definition.
“Survival” is the closest we have to an objective moral or rational determinant.
Whether or not a human survives is an objective question. The amount of hair they have is similarly objective. So is the amount of laughing they have done, or the amount of mathematical facts they know.
All of these have ambiguity of definition, has a braindead body with a beating heart “survived”? This is a question of how you define “survive”. And once you define that, its objective.
There is nothing special about survival, except to the extent that some part of ourselves already cares about it.
And evolution as a force typically acts on collectives, not individuals.
Evolution doesn’t effect any individual in particular. There is no individual moth who evolved to be dark. It acts on the population of moths as a whole. But evolution selects for the individuals that put themselves ahead. Often this means individuals that cheat to benefit themselves at the expense of the species. (Cooperative behaviour is favoured when creatures have long memories and a good reputation is a big survival advantage. Stab your hunting partner in the back to double your share once, and no one will ever hunt with you again.)
