Sounds mostly ok with me. You're correct to suspect that some (even legitimate evolutionary biologists) would balk at point #5. Natural selection is the primary mechanism in evolution, but it's not the only one. Genetic drift, a non-NS type mechanism, can produce new traits. Neutral evolution can maintain traits that are no longer adaptive, as long as they're not currently mal-adaptive (that is, neutral or invisible to NS). Other traits can evolve for one use but co-opted for another use (exaptation/co-option). Sexual selection, in so far as it is distinct from NS, sometimes works against NS.
