Morphological tree vs molecular tree

Analysing character convergence requires a species tree. Because the mammalian tree is not completely resolved, we used three trees, respectively, reconstructed using the morphological characters, molecular characters, and both types of characters in the data set. Under each tree, we inferred the ancestral states at all … See more Because the true mammalian tree is unknown, to ensure a fair comparison between morphological and molecular characters, we further examined every four species in the … See more Because the vast majority of molecular convergences are explainable by chance18,19,30,31, the fact that average morphological … See more We found that 75.2% of parsimony-informative morphological characters are binary (Fig. 3a). Because binary characters can only have one kind of change given an ancestral state, it is obvious that they are … See more We applied the above pipeline to the mammalian data set including both morphological characters and amino acid sequences.
