Sentence examples similar to hindlimb pelvic from inspiring English sources
Comparing the procellariiform body plan to that of pterosaurs may show why such data is scarce: procellariiform bodies are not particularly pterosaur-like (Figs. 4, 7) with longer, narrower wings that act independently of the hindlimbs, shorter necks, smaller heads and an entirely different pelvic and hindlimb morphology.
Interestingly, Livezey and Zusi ([4]: p. 48) noted that the majority of characters supporting a loon/grebe clade are from the pelvic girdle and hindlimb.
The first, "strong morphological support for a clade that unites the taxa that share the similar selective environment" ([143]: p.502), appears to be satisfied for loons and grebes, particularly with reference to characters in the pelvic girdle and hindlimb.
Tetrapod limb evolution involves the change of pectoral and pelvic fins into forelimbs and hindlimbs (arms and legs respectively).
Eels have also lost their pelvic fins, which are homologous structures to the hindlimbs of tetrapods (Burke and Rosa-Molinar, 2002).
E.g. it could have been that the movement of the pelvic girdle was different in controls, leading to less tail movement (even though the hindlimbs are in alternation for both controls and mutants).
It would be very good to have done the same analysis for the control animals and show that the tail/nose movements are inconsistent with passive movement, e.g. it could have been that the movement of the pelvic girdle was different in controls, leading to less tail movement (even though the hindlimbs are in alternation for both controls and mutants).
