What would Karl Popper say relevant to this exercise? Probably that
phylogenetic estimation is just historicism in reverse. One is projecting
backwards in time, following the expected effects of a historical "force,"
namely natural selection on gradually accumulating mutations, and expecting
that the result must be approximately correct in detail using some
particular method or notional modification of a method as is cited below by
Popper condemned historicism, dedicating his book "In memory of the
countless men and women of all creeds or nations or races who fell victims
to the fascist and communist belief in Inexorable Laws of Historical
Destincy." I guess he hadn't heard of cladistics yet.
