Provenance of individual bytes on tapes in a bff soup after 10,000, 500,000, 1.5 million, 2.5 million, 3.5 million, 6 million, 7 million, and 10 million interactions. The increasing role of self-modification in generating novelty is evident, culminating in the emergence (just before 6 million interactions) of a full-tape replicator whose parts are modified copies of a shorter imperfect replicator.
