The Figure Below Shows the Increasing Morphological Complexity in Crustacean

question 1

Multiple Choice

The figure below shows the increasing morphological complexity in crustacean legs in 12 different phylogenetic comparisons.Why did the authors of this study choose to analyze the data independently for each comparison?

• A)The lower sample size in each comparison makes for a more powerful statistical test.
• B)This methods allows testing for species selection within each of the 12 comparisons.
• C)The observed pattern allows the exclusion of species selection as a possible evolutionary mechanism.
• D)This method controls for phylogenetic correlations.
