Previous studies have shown that while hoxa2a of the Japanese medaka (Oryzias latipes) shows a conserved expression pattern in the hindbrain and PAs to other osteichthyan Hoxa2 genes, medaka hoxa2b was shown to be a pseudogene, [psi]hoxa2b, which is expressed in non-canonical Hox PG2 domains, including the embryonic trunk and the pectoral fin buds.

Schultze also supported Gross's position that Andreolepis is the most primitive actinopterygian and considered (Schultze 1996, p.222) Lophosteus the earliest osteichthyan which cannot be placed among either the actinopterygians or sarcopterygians.
