Heh, now you're adding periodical 'updates' to hide the DNA/fossil evidence, while I understood your original premise to be a pre-existing world based on one old seeding, followed by a far more recent 'adjusting' using the Chicxulub meteor to clear the playing field for the Mars exodus. Someone more knowledgeable than me might calculate how often those 'updates' would need to be done to hide artificial changes in DNA history. Fun idea though.
