code, Protrusion data

For both the gape data and the jaw protrusion data, the model treating parrotfish clade as a separate regime using ouch (differing optima) is not supported (even though it does have better AIC score for the protrusion data). The model using my new method allowing alpha and sigma to differ is strongly supported, providing support for the “release of constraint” hypothesis.
