Evolutionists now increasingly believe that major adaptations are driven by neutral mutations.
Of course finches don’t multiply and cycle through generations as rapidly as bacteria. Still, these birds have been isolated on the iconic islands for some 2 million years.
Lenski agrees that the beneficial mutations seen in his Long Term Evolution Experiment are overwhelmingly degradative or loss-of-function ones.
Perhaps the evidence for the vast scope of Darwin’s theory really isn’t as strong as biologists over the years have been telling each other.
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.
