Of course, if we're going to get fussy about about homology of terminology,
and when ideas originated, it should be pointed out that Walter Zimmerman
(a Botanist!), is generally believed to have preceded Willi Hennig with
many of "Hennig's" ideas of cladistics (at least in an unrefined form)....
Some even go so far as to intimate that Hennig borrowed heavily from
Zimmerman, while giving him little credit....
(Just having fun stirring the pot a little more--it makes for a more
flavorful stew.)
