A hyostylic jaw suspension in chondrichthyans allows protrusion of the upper jaw independent of the lower jaw
Evolutionary biologists have assumed that the ability to protrude the upper jaw is advantageous for feeding—in other words, that it is an adaptive derived character. An alternative hypothesis is that a hyostylic jaw suspension is a neutral ancestral character (i.e., one that is neither advantageous nor disadvantageous). These two hypotheses (i.e., hyostylic jaw is advantageous/hyostylic jaw is neutral) generate different predictions about the phylogenetic distribution of hyostyly. What are those predictions, and which one is supported by the phylogenetic distribution of hyostyly?
