Because RMNS model has no predictory power, there is no way falsifying it, and you cannot prove it wrong by scientific methods. In other words, it stands in any outcomes. By Popperian criteria, Neo-Darwinism is a pseudo-science.
Not only would a truly altruisitic species falsify the theory, as Darwin and another posted noted, but so would a common creationist epithet for evolution.
Have you ever heard of evolution through RMNS described as "Dogs giving birth to cats evolution"? I have, from one of my best friends. And I didn't say it at the time but I will next time she says it: such an event (in a repeatable or authortatively documented example) would completely falsify the entire New Synthesis of evolution, the dominant paradigm since the 1920's and 1930's. Animals are not supposed to change families in one go like that, according to the theory.
Note that there is no necessary reason that either an Intelligent Designer or a literal Book of Genesis universe would need to obey such laws- in both cases it would be because the Designer/God made it so- so such an event would not falsify either theory. The search for a hypothetical fact that would falsify either of those theories continues.
