When Charles Darwin proposed his theory of evolution in 1859 there were many scientific problems with the idea. Today, a century and a half later, we know of a great many more empirical challenges to the idea that the species arose spontaneously. The latest falsified expectation is that microRNAs, discovered only a few decades ago, when compared between different species do not align with the evolutionary tree. Evolutionist Kevin Peterson and colleagues are pursuing this research. “I've looked at thousands of microRNA genes,” explains Peterson, “and I can't find a single example that would support the traditional tree.”
While there remain questions about these new phylogenetic data, “What we know at this stage,” explains another evolutionist, “is that we do have a very serious incongruence.” In other words, different types of data report very different evolutionary trees. The conflict is much greater than normal statistical variations.
“There have to be,” adds another evolutionist, “other explanations.” One explanation is that microRNAs evolve in some unexpected way. Another is that the traditional evolutionary tree is all wrong. Or evolutionists may consider other explanations. But in any case, microRNAs are yet another example of evidence that does not fit evolutionary expectations. Once again, the theory will need to be modified in complex ways to fit the new findings.
It isn’t that any one particular finding falsifies evolution, but the consistent pattern of contradictory findings—from nature’s complexities to uncooperative patterns—show that evolution is not explanatory, but rather tautological.
