Maybe, like modern human anatomists they needed to sell new editions
of their books - so renamed and reclassified groups and organisms.
(What is the other use of from time to time change the name of the
kneepan from patella to rotula and vice-versa? Or to rename chicken
from _Phasianus gallus_ to _Gallus gallus_?)

(Well of course there was some new organisms that do not fit well in
any previous groups; some organisms that after more careful analysis
must be reclassified; some trash bin groups that needed to be tidied
up; some inconsistencies generated by synonymies, divergent
interpretations and so on.)
