Just look at those graphs of distributions for speciation times. Reading the description of the "speciation clock", i would have imagined a sharp distribution with a very tall peak at 2 million years. Yes, the mode is about 2 million years. But the distribution is veeery broad. Looking at the graphs, there is no reason to believe that whales and flies have similar speciation times. A very misleading description, unfortunately quite typical of the scientific news cycle.
