While perhaps not immediately pertinent to the problem, the emergence of sexual reproduction is credited as a major factor in the explosion of variation in multicellular organisms. Part of the advantage, ironically, is that sexual reproduction is a rather large burden compared to evolutionary strategies that came before. The fact that sexual reproduction is so challenging perhaps ensures that less is left to chance by filtering out individuals that cannot meet the burden and rewarding those that tend to be better at achieving reproduction itself. Likely there is some relation between improved reproductive success and some novel traits that helped to achieve it. I don't have the knowledge to weigh in on AI analogs, but I could imagine roughly a strategy that involves co-related burdens and goals to improve the chances of choosing the right individuals.
