ABSTRACT
The indiscriminate application of phylogenetically based comparative methods in cross-species
correlated evolution analyses has been questioned. It has been argued that traits are not always
significantly correlated to their phylogenetic history, and that correcting for phylogeny in these
cases may be unnecessary and may even introduce statistical error. Statistical diagnostics to test
for phylogenetic signal have recently been presented. Here, we investigate the relationship
