For which of the following studies would you recommend the use of Felsenstein’s method of phylogenetically independent contrasts? Why?
a. A comparison of feather parasite burden and beak shape in different species of birds.
b. An experiment that tests whether birds whose beak shapes are experimentally altered will end up with greater parasite loads (similar to Clayton et al.’s study).
c. An observational study that measures the correlations among beak shape of individual birds with their preening behavior, and with their parasite loads
