Can Mutations Add Information?
It is an interesting concept, but is there any proof that it could happen? We should first come up with a prediction or hypothesis based on what we would expect to observe if mutations could add information. Let’s outline very specifically what the claim is and describe what we would expect to see:
The Idea:
Billions of years ago, a single-cell bacteria (with complex DNA) spontaneoulsy generated and came to life. As this bacteria’s DNA replicated, a mistake occurred during the copying process. This mistake transferred to future generations and additional mistakes occurred in their DNA. Eventually, all of these collective random mistakes caused the bacteria to evolve into more complex, multi-cellular organisms. Given enough time (the miraculous ingredient for evolution), through these unguided random errors, the bacteria created a complex system of sexual reproduction. In order to accomplish this, the male and female organisms evolved independently but in perfect alignment so their sexual reproductive processes became compatible with one another within one lifetime (otherwise how would they survive?). These creatures’ offspring continued to generate millions of mutations that increased information in their DNA and lead to more and more biological functions and features. Each time a new type of organism evolved, a sexual counterpart evolved (again, randomly) in order for that organism to survive and reproduce. The random nature of this change with no guiding process caused trillions upon trillions of mutations (only a fraction of the mutations resulted in something useful). For every new kind of organism that was created “successfully” through this process, there were millions of predecessors to that organism that were less “fit” and eventually died off. At any point in time throughout the history of the world, billions upon billions of different types of insects, plants and animals would be observed in the process of evolving into something else until the right kind of mutation occurred to create something stable and suitable for survival.
To summarize, if evolution were true, this is what we would expect to observe today:
- Partially evolved creatures everywhere. In fact, creatures that appear “fully formed” and not in transition would be extremely rare. How would an unguided evolutionary process know when to stop? It is impossible – it would simply continue to grow like cancer unless acted upon by another force.
- It would be possible to view the DNA for any of these creatures in a lab and observe how all of the past mutations resulted in more advanced and improved information in the genome. It would be possible to watch lab rats or fruit flies evolve (replicate small scale evolution in a lab).
- Fossils for intermediate species would be abundant as well as living examples of intermediate species all around us.
- You would not expect to see complexity that can’t be explained by mutations.
