Palaeos Vertebrates 120.600 Euteleosti: Neognathi |
 | | Briefly, it appears that almost all of the esociforms were subject to severe selection for cold and drought tolerance in the recent geologic past, which can do very odd things to structures of metabolic proteins. |
 | | Further, the polarity of the characters used by Wilson and Veilleux is suspect because the position of esociforms within the teleosts was unknown. |
 | | At the time, it was believed that Esociforms (usually referred to as "Esocoidei" in the older literature), were either a kind of salmoniform (as assumed by Wilson and Veilleux), or were even more basal -- perhaps even the sister of Euteleostei. |
