A species where ALL members self-sacrifice in order to save the group has obvious advantages over a cutthroat society. That I will not debate against. However, it doesn't seem like you consider how a species could reach such a point if morality, altruism, and self-sacrifice are emergent attributes that derive from evolution. Morality is not an evolutionary advantage on the individual level. Were one moral being to emerge amongst an amoral species, he would certainly not derive any evolutionary fitness from his morality. Quite the contrary. He would lose evolutionary fitness as he would be regularly taken advantage of. How this society eventually becomes fully moral in your mind is a mystery to me.
If my opinion that evolution promotes traits which are individually beneficial and literally could not care less how the survival or death of any individual affects the evolution of a species is entirely false as you say, it should be child's play for you to spout off a list of attributes other than altruism that evolution jumps through all of these hoops with.
Recursive algorithm, huh? You're saying evolution doesn't have to consider anything because now apparently evolution is some vaguely computer-like entity that can behave intelligently yet is not self-aware. This isn't an explanation. This is lawyering.
From wikipedia:
Moral realism (also
ethical realism) is the position that
ethicalsentences express
propositions that refer to objective features of the world (that is, features independent of subjective opinion), some of which propositions may be true to the extent that they report those features accurately.

All of this becomes irrelevant when you consider aggregate genetics and probability genes as i explained later in the post. Individual advantage doesn't necessarily matter as i've shown, and you've already agreed that self sacrifice is good for a species' survival. Here's a theoretical way it could emerge initially though: one hominid ancestor develops a gene which gives him a low probability of having a tendency to self sacrifice, but since genes are often interconnected it probably made also him more social or something. Since he has above average social skills, (or some other positive trait) he reproduces more and leads to a lineage of humans with a gene that gives low probability for self sacrifice in addition to something else (maybe immunity to some disease, or moreintellect). This gene, over time, is introduced into a larger population.
Since only a small number of these humans will sacrifice initially due to the low probability, it wouldn't stop this gene from becoming more prominent in the average population since there is a another good individualistic advantage associated with it. But because some minority of humans do self sacrifice at that point, albeit a tiny amount, the groups that does have those people will do better than those without the genetic variant. Suddenly now have large scale evolution where groups which self sacrifice more survive more, and therefore natural selection allows those groups to eventually become modern day humans.
Now its what you would call jumping through hoops, but explanations like this are certainly possible. Unless you have intelligent design somewhere in there how else do you explain the early hominid tendency for self sacrifice and altruism? If evolution can offer an explanation to it then i'd bet on evolution since it has been highly reliable in the past. Moral realism certainly doesn't explain it, or if it does that definition doesn't show how. All the definition is saying is that some propositions are true because they reflect features accurately. Sounds like a tautology instead of an explanation. And everything regarding morality is subjective anyways. Its all a matter of interpretation.
If my opinion that evolution promotes traits which are individually beneficial and literally could not care less how the survival or death of any individual affects the evolution of a species is entirely false as you say, it should be child's play for you to spout off a list of attributes other than altruism that evolution jumps through all of these hoops with.
The amount of things I can list off has nothing to do with the validity of my argument. But I also didn't claim that evolution doesn't promote traits that are also individualistically beneficial. Some traits can be individual and some can be aggregate. It need not be mutually exclusive. And some species are more dependent on aggregate evolution than the others. And jumping through hoops? Have you seen videos demonstrating the inner workings of the cell? Many, many things about genetics, protein folding, mitochondria, etc are all extremely complicated.
But ill list some more traits anyways: superstition, intelligence (its why its very difficult to breed intelligence in mice for example), the immune system, etc.
You also didn't address anything about aggregate gene pools and probabilities, which i thought would be fairly convincing, even without my hypothetical scenario describing how the trait of self sacrifice could get started. I argued how aggregate gene pools and probabilistically determined traits for a species can maintain specific traits even when members of the species with certain traits die off; the traits were a result of probability rather than directly from a certain mutation that was only particular to that one organism. The way these probabilities could change, which i though you might address, is that differences between groups within the average (in other words different probability groups) survive and reproduce more over the other groups, therefore changing the average probabilities over time. Its evolution still, but its at a larger scale and is more complicated/sophisticated than simple individualistic
Recursive algorithm, huh? You're saying evolution doesn't have to consider anything because now apparently evolution is some vaguely computer-like entity that can behave intelligently yet is not self-aware. This isn't an explanation. This is lawyering.
If using the definitions of words and drawing an analogy is now "lawyering", i guess I am. Recursive means that the current state of the algorithm is fed back through the inputs, which changes it, then outputs it again, which is then fed back to the inputs and so on.
"Considering" implies a mind or intention, and evolution has neither. It is a logical process of selection for traits that produce survivability. The algorithm part comes in because a mutation is introduced randomly into an organism, which is then copied. Its recursive because the first organism has information which is fed into the inputs of the evolution algorithm, and then the copy of organism that is the output, which then feeds into the inputs of the evolution algorithm during reproduction, and therefore produces another organism as an output and so on. Death results in the end of a recursive sequence. it produces a binary tree that you would also expect to see in a recursive computer algorithm. They're similar in many ways. This is an explanation for how evolution is not as simple as random chance and how evolution might appear to consider things, but doesn't.
You can actual simulate evolution of a computer by creating programs which have random mutations and compete for cpu and memory resources. These are inherently recursive algorithms.
