 A pity, it seemed so logical. But after seeing that comment about the
undemonstrated founder effect made more than once by Michael Heads, I
would like to add that on the other hand there are scientists happily
reporting phylogenetic evidence for marine animal speciation via the
broader process of _founder dispersal_, whilst also taking into account
the vicariance speciation possibilities that Michael much prefers .
