A common question brought up about evolution, and also a common criticism of evolution, is “Is evolution falsifiable?” In today’s post I will attempt to answer this question with a few examples of how evolution can be falsified, keeping in mind that there are so many more possible ways to disprove evolution that I will not blog about, but may sometime in the future.
I will also first say that this question shows the ignorance that most creationists have of evolution, they want to be able to have one fowl swoop which will disprove the theory, and also one piece of evidence which proves their theory. This is quite impossible because evolution is such a grand theory with so many lines of evidence pointing towards it, that pointing to one fossil or one gene and saying “There, that disproves evolution!” is just not going to be done.
It is also true that the window for disproof of evolution has fully passed, about 150 years ago is when these falsifications were needed, because now we have all this time under our belts of proof of evolution, everything we find pointing to evolution, that any ‘disproof’ of evolution would be disregarded, because of all of the evidence which says that evolution happened. When evolution was first being tested 150 years ago, there were millions of times where evolution could have been disproved, but it wasn’t.
Another and most common possible falsification for evolution is finding the fossil of a species in a strata very different to where it should be, the classic example is ‘horses in the Cambrian.’ and this would raise some serious doubts about evolution. But this fossil would have to be checked for fraud and hoaxing many times over before it would be believed, because Occam’s razor does come in to play.
The biggest disproof of common descent would also be to find a species where you cannot trace its ancestry back up the evolutionary tree back to its roots, a species which does not fit into the grand scheme of evolution, but looks like it comes from its own little side tree of evolution. If one day, on an expedition through uncharted parts of the amazon, we find some animals which do not look anything like any of the species we currently have today, thatmight puncture a hole in the evolutionary theory.
That’s all for today, I will leave you with a quote from Charles Darwin, “It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.” Charles Darwin, an English naturalist of some note.
