But - if evolution was falsified by DNA sequencing not showing evidence of common descent, if the fossil record didn't show evidence of gradually progressive complexity in species through time (that's a simplified statement, but accurate enough here), if animal species were scattered 'helter skelter' in the geologic column like rabbits found with dinosaurs, birds found before reptiles etc., if all dating methods didn't show evidence of a really old earth and universe, if there were no atavisms ("throwbacks"), no vestigial features, no signs of retroviral insertion points in DNA that must have occurred in a shared ancestor... To put it short, if the theory of evolution did not describe what we see in nature, then it would be falsified, and we'd have to look elsewhere for an explanation.
The problem is that evolutionary theory is so flexible that evolutionists simply change it to prevent it from being falsified by any certain line of data. Often this results in evolution being retreated into unfalsifiability in the particular specific area. ReMine (who is not specifically a Bibilical creationist) documents several instances of this and concludes that evolution is now either falsified or unfalsifiable depending on how its defined. His book The Biotic Message should be read by anyone who really wishes to fully understand evolution: contents: http://saintpaulscience.com/contents.htm (available from www.creationresearch.org)
That in and of itself would not mean everyone would have jumped on a literal reading of the Bible, but it would perhaps have become a story that was easier to swallow scientifically.
