But of course most speciation now is in fact thought to occur through
random variation and random fixation rather than by selection as
Darwin thought. There's good reason to think that some speciation is
due to selection, but not much. I worry that we think only that
Darwinian evolution is about selection (natural or sexual), when in
fact another really deep aspect of his view is common descent, and
this is not tied now to selection.
