We looked at some papers claiming to see evolution happening in real time, to see if natural selection has actually invented a new function, or just broke an existing function.
There are many solid, trustworthy inferences in modern science, but there are those that are not very trustworthy at all.
Evolutionists now increasingly believe that major adaptations are driven by neutral mutations.
Lenski agrees that the beneficial mutations seen in his Long Term Evolution Experiment are overwhelmingly degradative or loss-of-function ones.
Their review pretty much completely misses the mark. Nonetheless, it is a good illustration of how sincere-yet-perplexed professional evolutionary biologists view the data.
