First, if evolution is true, we must believe that the basic mutation rate varies by more than an order of magnitude in different bacteria:
Upon comparing 34 Escherichia coli genomes, we observe that the neutral mutation rate varies by more than an order of magnitude across 2,659 genes, with mutational hot and cold spots spanning several kilobases.
The next result is that, under evolution, the variation between different mutation rates must not be random, but rather must follow a rational pattern:
Importantly, the variation is not random: we detect a lower rate in highly expressed genes and in those undergoing stronger purifying selection.
And so, given evolution, we must conclude that evolution has optimized the mutation rate:
Our observations suggest that the mutation rate has been evolutionarily optimized to reduce the risk of deleterious mutations.
Of course there is no known mechanism that could do this:
Current knowledge of factors influencing the mutation rate—including transcription-coupled repair and context-dependent mutagenesis—do not explain these observations, indicating that additional mechanisms must be involved.
But evolutionists will think of something, no matter how speculative.
The findings have important implications for our understanding of evolution and the control of mutations.
In other words, results that rebuke a fundamental concept of evolution, and that cannot even be explained by evolutionists (who are notorious for being able to explain anything with their just-so stories), are presented by evolutionists as important findings for understanding how evolution works. It is all about those veering atoms.
