$4.$ Consider the proofreading function of DNA Polymerase. Imagine that there was a very ancient organism that was somehow able to increase its ability to identify and fix DNA replication errors $1000$X more efficiently than the usual ability to catch errors. Since this was a very ancient organism, it would have had to evolve so it could adapt to many changes in its environment over the millennia. What would be the most likely fate of this ancient organism today? A$)$ The organism would be very similar today to what it was long ago because it had so few mutations over the millennia. B$)$ The organism would be extinct because it did not have a high enough mutation rate to generate individuals that could adapt to the changes in its environment over the millennia. C$)$ Neither of these possibilities are plausible. D$)$ Both of these possibilities are plausible.
