Zinov'ev, A.V. 2007. Apparat dvunogoi lokomotsii kukushkoobraznykh (Cuculiformes): stsenarii adaptivnoi evolyutsii. Zoologičeskij žurnal 86 (10): S1250-1258.
"The apparatus of bipedal locomotion of the cuckoo-like [birds] (Cuculiformes): scenarios of adaptive evolution". That sounds good. If the author is who I think he is, that's good, too. :-)
PS: A funny quote from Sibley and Ahlquist (1973): Stresemen (1965) would have say that "If Opisthocomus is related to the gallinaceous birds it is only by way of Adam and Eve". Quite a statement ! XD
:-D :-D :-D
