Morphometricians,
Id like to gather some opinions on measuring phylogenetic signal from GM data. For many GM analyses, size-free shape data (e.g., residuals from a regression) are used in analyses of variation/covariation. However, I less often see size and shape analyzed independently when measuring phylogenetic signal. If most of the shape variation is allometric, it would seem that the phylogenetic signal for uncorrected shape variables may approach the strength of the phylogenetic signal for size alone. However, I have not found this to be the case with several datasets. Has anyone examined this in detail?
