Extended Data Fig. 7: Extreme morphologies and spread along lines of least resistance for each family within the parvorder Passeroidea in our sample.

Within-family maximum Procrustes distances for PLS1scores (situation 2) for both beak and skull blocks. Done for all the families that include two or more species in our sample. Legend for labels in Extended Data Table 2. Dot colours correspond to the ages of the most common recent ancestor (MRCA) for each of the focal families in our MCC tree.
