In Mayr's book What Evolution Is, he discusses about normalizing selection in rapidly evolving lineages.

"However, normalizing selection is equally active in rapidly evolving lineages."

What is meant by "rapidly evolving lineages" and what examples can be found about either the rate of evolution in population where normalizing selection is the dominant evolutionary process or the fact that normalizing selection can lead to speciation. How important is normalizing selection compared to disruptive and directional selection?

    $\begingroup$ As indicated by the leading "However...", I suspect that this question is going to be a lot easier to answer if we get some more context about this statement. Looking at the statement in context [here][google.com/books/edition/What_Evolution_Is/…, it looks like "rapidly evolving lineages" means literally everything that isn't a living fossil! $\endgroup$ Mar 29 at 19:06
