Delayed adulthood has already occurred, in some sense, in humanity. Homo sapiens is a neotenous[0] species already, meaning that compared to similar species, we are more similar to their juvenile than mature states. It's speculative, but I wonder if there could be a connection between delayed adulthood and lengthening lifespans. It "makes sense" in the common-sense meaning that if we stretch out our lifespan, it would also stretch out the various stages of life.
